Mathematics for Machine Learning (Free PDF)

 

The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.

Probabilistic Machine Learning: An Introduction (Adaptive Computation and Machine Learning series) (Free PDF)

 

A detailed and up-to-date introduction to machine learning, presented through the unifying lens of probabilistic modeling and Bayesian decision theory.

This book offers a detailed and up-to-date introduction to machine learning (including deep learning) through the unifying lens of probabilistic modeling and Bayesian decision theory. The book covers mathematical background (including linear algebra and optimization), basic supervised learning (including linear and logistic regression and deep neural networks), as well as more advanced topics (including transfer learning and unsupervised learning). End-of-chapter exercises allow students to apply what they have learned, and an appendix covers notation.

Probabilistic Machine Learning grew out of the author’s 2012 book, Machine Learning: A Probabilistic Perspective. More than just a simple update, this is a completely new book that reflects the dramatic developments in the field since 2012, most notably deep learning. In addition, the new book is accompanied by online Python code, using libraries such as scikit-learn, JAX, PyTorch, and Tensorflow, which can be used to reproduce nearly all the figures; this code can be run inside a web browser using cloud-based notebooks, and provides a practical complement to the theoretical topics discussed in the book. This introductory text will be followed by a sequel that covers more advanced topics, taking the same probabilistic approach.

a = 10 if a = 30 or 40 or 60 : print('Hello') else : print('Hi')

Code :

a = 10

if a = 30 or 40 or 60 :

print('Hello')

else :

print('Hi')

Solution and Explanation:

Answer : Error

The equality comparison should use == instead of =. Second, you need to compare the variable a against each value separately. Here's the corrected version:

a = 10

if a == 30 or a == 40 or a == 60:

    print('Hello')

else:

    print('Hi')

This way, it checks if a is equal to any of the specified values (30, 40, or 60) and prints 'Hello' if true, otherwise, it prints 'Hi'.

Improving your statistical inferences (Free Course)

 

There are 8 modules in this course

This course aims to help you to draw better statistical inferences from empirical research. First, we will discuss how to correctly interpret p-values, effect sizes, confidence intervals, Bayes Factors, and likelihood ratios, and how these statistics answer different questions you might be interested in. Then, you will learn how to design experiments where the false positive rate is controlled, and how to decide upon the sample size for your study, for example in order to achieve high statistical power. Subsequently, you will learn how to interpret evidence in the scientific literature given widespread publication bias, for example by learning about p-curve analysis. Finally, we will talk about how to do philosophy of science, theory construction, and cumulative science, including how to perform replication studies, why and how to pre-register your experiment, and how to share your results following Open Science principles. 

In practical, hands on assignments, you will learn how to simulate t-tests to learn which p-values you can expect, calculate likelihood ratio's and get an introduction the binomial Bayesian statistics, and learn about the positive predictive value which expresses the probability published research findings are true. We will experience the problems with optional stopping and learn how to prevent these problems by using sequential analyses. You will calculate effect sizes, see how confidence intervals work through simulations, and practice doing a-priori power analyses. Finally, you will learn how to examine whether the null hypothesis is true using equivalence testing and Bayesian statistics, and how to pre-register a study, and share your data on the Open Science Framework.

What will be the output of the following code snippet? num1 = num2 = (10, 20, 30, 40, 50) print(id(num1), type(num2)) print(isinstance(num1, tuple)) print(num1 is num2) print(num1 is not num2) print(20 in num1) print(30 not in num2)

What will be the output of the following code snippet?

num1 = num2 = (10, 20, 30, 40, 50)

1. print(id(num1), type(num2))
2. print(isinstance(num1, tuple))
3. print(num1 is num2)
4. print(num1 is not num2)
5. print(20 in num1)
6. print(30 not in num2)

Solution and Explanation: 

num1 and num2 are both assigned the same tuple (10, 20, 30, 40, 50).

1. print(id(num1), type(num2)) prints the identity and type of num1. Since num1 and num2 reference the same tuple, they will have the same identity. The output will show the identity and type of the tuple.
2. print(isinstance(num1, tuple)) checks if num1 is an instance of the tuple class and prints True because num1 is a tuple.
3. print(num1 is num2) checks if num1 and num2 refer to the same object. Since they are both assigned the same tuple, this will print True.
4. print(num1 is not num2) checks if num1 and num2 do not refer to the same object. Since they are the same tuple, this will print False.
5. print(20 in num1) checks if the value 20 is present in the tuple num1. It will print True.
6. print(30 not in num2) checks if the value 30 is not present in the tuple num2. It will print False.

The output of the code will look something like this:

(id_of_tuple, <class 'tuple'>)

True

True

False

True

False

num1 = [10, 20] num2 = [30] num1.append(num2) print(num1)

Code - 

num1 = [10, 20]

num2 = [30]

num1.append(num2)

print(num1)

Solution and Explanation :

The above code appends the list num2 as a single element to the list num1. So, num1 becomes a nested list. Here's the breakdown of the code:

num1 = [10, 20]

num2 = [30]

num1.append(num2)

print(num1)

num1 is initially [10, 20].

num2 is [30].

num1.append(num2) appends num2 as a single element to num1, resulting in num1 becoming [10, 20, [30]].

print(num1) prints the updated num1.

The output of the code will be: [10, 20, [30]]

Python Coding challenge - Day 75 | What is the output of the following Python code?

 

Code : 

lst = [10, 25, 4, 12, 3, 8]

sorted(lst)

print(lst)

Solution and Explanation :

The above code sorts the list lst using the sorted() function, but it doesn't modify the original list. The sorted() function returns a new sorted list without changing the original list. If you want to sort the original list in-place, you can use the sort() method of the list:

lst = [10, 25, 4, 12, 3, 8]

lst.sort()

print(lst)

This will modify the original list lst and print the sorted result. If you want to keep the original list unchanged and create a new sorted list, you can use sorted() and assign it to a new variable:

lst = [10, 25, 4, 12, 3, 8]

sorted_lst = sorted(lst)

print(sorted_lst)

print(lst)

In this case, sorted_lst will contain the sorted version of the original list, and lst will remain unchanged.

num = [10, 20, 30, 40, 50] num[2:4] = [ ] print(num)

Code :

num = [10, 20, 30, 40, 50]

num[2:4] = [ ]

print(num)

Solution and Explanation : 

In the provided code, you have a list num containing the elements [10, 20, 30, 40, 50]. Then, you use slicing to modify elements from index 2 to 3 (not including 4) by assigning an empty list [] to that slice. Let's break down the code step by step:

num = [10, 20, 30, 40, 50]

This initializes the list num with the values [10, 20, 30, 40, 50].

num[2:4] = []

This line modifies the elements at index 2 and 3 (not including 4) by assigning an empty list [] to that slice. As a result, the elements at index 2 and 3 are removed.

After this operation, the list num will be:

[10, 20, 50]

So, the final output of print(num) will be: [10, 20, 50]

1. print(6 // 2) 2. print(3 % -2) 3. print(-2 % -4) 4. print(17 / 4) 5. print(-5 // -3)

1. print(6 // 2)

2. print(3 % -2)

3. print(-2 % -4)

4. print(17 / 4)

5. print(-5 // -3)

Let's evaluate each expression:

print(6 // 2)

Output: 3

Explanation: // is the floor division operator, which returns the largest integer that is less than or equal to the result of the division. In this case, 6 divided by 2 is 3.

print(3 % -2)

Output: -1

Explanation: % is the modulo operator, which returns the remainder of the division. In this case, the remainder of 3 divided by -2 is -1.

print(-2 % -4)

Output: -2

Explanation: Similar to the previous example, the remainder of -2 divided by -4 is -2.

print(17 / 4)

Output: 4.25

Explanation: / is the division operator, and it returns the quotient of the division. In this case, 17 divided by 4 is 4.25.

print(-5 // -3)

Output: 1

Explanation: The floor division of -5 by -3 is 1. The result is rounded down to the nearest integer.

a = [1, 2, 3, 4] b = [1, 2, 5] print(a < b)

 In Python, when comparing lists using the less than (<) operator, the lexicographical (dictionary) order is considered. The comparison is performed element-wise until a difference is found. In your example:

a = [1, 2, 3, 4]

b = [1, 2, 5]

print(a < b)

The comparison starts with the first elements: 1 in a and 1 in b. Since they are equal, the comparison moves to the next elements: 2 in a and 2 in b. Again, they are equal. Finally, the comparison reaches the third elements: 3 in a and 5 in b. At this point, 3 is less than 5, so the result of the comparison is True.

Therefore, the output of the code will be: True

Python Coding challenge - Day 74 | What is the output of the following Python code?

 

Code - 

fruits = {'Kiwi', 'Jack Fruit', 'Lichi'}

fruits.clear( )

print(fruits)

Solution and Explanation: 

The variable fruits seems to be defined as a set, but you are trying to use the clear() method on it, which is applicable to dictionaries, not sets. If you want to clear a set, you can use the clear() method directly on the set. Here's the corrected code:

fruits = {'Kiwi', 'Jack Fruit', 'Lichi'}

fruits.clear()

print(fruits)

This will output an empty set:

set()

If you intended fruits to be a dictionary, you should define it using key-value pairs, like this:

fruits = {'kiwi': 1, 'jackfruit': 2, 'lichi': 3}

fruits.clear()

print(fruits)

This will output an empty dictionary:

There are 4 modules in this course

The practice of investment management has been transformed in recent years by computational methods. Instead of merely explaining the science, we help you build on that foundation in a practical manner, with an emphasis on the hands-on implementation of those ideas in the Python programming language. In this course, we cover the estimation, of risk and return parameters for meaningful portfolio decisions, and also introduce a variety of state-of-the-art portfolio construction techniques that have proven popular in investment management and portfolio construction due to their enhanced robustness.

As we cover the theory and math in lecture videos, we'll also implement the concepts in Python, and you'll be able to code along with us so that you have a deep and practical understanding of how those methods work. By the time you are done, not only will you have a foundational understanding of modern computational methods in investment management, you'll have practical mastery in the implementation of those methods. If you follow along and implement all the lab exercises, you will complete the course with a powerful toolkit that you will be able to use to perform your own analysis and build your own implementations and perhaps even use your newly acquired knowledge to improve on current methods.

Inferential Statistical Analysis with Python

 

What you'll learn

Determine assumptions needed to calculate confidence intervals for their respective population parameters.

Create confidence intervals in Python and interpret the results.

Review how inferential procedures are applied and interpreted step by step when analyzing real data.

Run hypothesis tests in Python and interpret the results.

There are 4 modules in this course

In this course, we will explore basic principles behind using data for estimation and for assessing theories. We will analyze both categorical data and quantitative data, starting with one population techniques and expanding to handle comparisons of two populations. We will learn how to construct confidence intervals. We will also use sample data to assess whether or not a theory about the value of a parameter is consistent with the data. A major focus will be on interpreting inferential results appropriately.  

At the end of each week, learners will apply what they’ve learned using Python within the course environment. During these lab-based sessions, learners will work through tutorials focusing on specific case studies to help solidify the week’s statistical concepts, which will include further deep dives into Python libraries including Statsmodels, Pandas, and Seaborn.

s = { } t = {1, 4, 5, 2, 3} print(type(s), type(t))

s = { }

t = {1, 4, 5, 2, 3}

print(type(s), type(t))

<class 'dict'> <class 'set'>

The first line initializes an empty dictionary s using curly braces {}, and the second line initializes a set t with the elements 1, 4, 5, 2, and 3 using curly braces as well.

The print(type(s), type(t)) statement then prints the types of s and t. When you run this code, the output will be:

<class 'dict'> <class 'set'>

This indicates that s is of type dict (dictionary) and t is of type set. If you want s to be an empty set, you should use the set() constructor:

s = set()

t = {1, 4, 5, 2, 3}

print(type(s), type(t))

With this corrected code, the output will be:

<class 'set'> <class 'set'>

Now both s and t will be of type set.

s1 = {10, 20, 30, 40, 50} s2 = {10, 20, 30, 40, 50} s3 = {*s1, *s2} print(s3) Output {40, 10, 50, 20, 30}

 s1 = {10, 20, 30, 40, 50}

s2 = {10, 20, 30, 40, 50}

s3 = {*s1, *s2}

print(s3)

Output

{40, 10, 50, 20, 30}

In the provided code, three sets s1, s2, and s3 are defined. s1 and s2 contain the same elements: 10, 20, 30, 40, and 50. Then, s3 is created by unpacking the elements of both s1 and s2. Finally, the elements of s3 are printed.

Here's the step-by-step explanation:

s1 is defined as the set {10, 20, 30, 40, 50}.

s2 is defined as the set {10, 20, 30, 40, 50}, which is the same as s1.

s3 is defined as the set resulting from unpacking the elements of both s1 and s2 using the * operator. This means that the elements of s1 and s2 are combined into a new set.

The print statement prints the elements of the set s3.

Since sets do not allow duplicate elements, the resulting set s3 will still have only unique elements. In this case, the output of the code will be:

{10, 20, 30, 40, 50}

Python Coding challenge - Day 73 | What is the output of the following Python code?

 

Code - 

i, j, k = 4, -1, 0

w = i or j or k      # w = (4 or -1) or 0 = 4

x = i and j and k    # x = (4 and -1) and 0 = 0

y = i or j and k     # y = (4 or -1) and 0 = 4

z = i and j or k     # z = (4 and -1) or 0 = -1

print(w, x, y, z)

Solution and Explanation - 

Here's the explanation for each variable:

w: It takes the first non-zero value from left to right in the sequence (i, j, k). In this case, the first non-zero value is 4.

x: It takes the first zero value from left to right in the sequence (i, j, k). In this case, the first zero value is 0.

y: It takes the first non-zero value from left to right in the sequence (i, j) and then evaluates the result with k using the "and" operator. In this case, (4 or -1) evaluates to 4, and 4 and 0 evaluates to 0.

z: It takes the first non-zero value from left to right in the sequence (i, j) and then evaluates the result with k using the "or" operator. In this case, (4 and -1) evaluates to -1, and -1 or 0 evaluates to -1.

So, the output of the print statement will be: 4 0 4 -1

Write a program to generate all Pythagorean Triplets with side length less than or equal to 50.

 Certainly! Let me explain the code step by step:

# Function to check if a, b, c form a Pythagorean triplet

def is_pythagorean_triplet(a, b, c):

    return a**2 + b**2 == c**2

This part defines a function is_pythagorean_triplet that takes three arguments (a, b, and c) and returns True if they form a Pythagorean triplet (satisfy the Pythagorean theorem), and False otherwise.

# Generate and print all Pythagorean triplets with side lengths <= 50

for a in range(1, 51):

    for b in range(a, 51):

Here, two nested for loops are used. The outer loop iterates over values of a from 1 to 50. The inner loop iterates over values of b from a to 50. The inner loop starts from a to avoid duplicate triplets (e.g., (3, 4, 5) and (4, 3, 5) are considered duplicates).

        c = (a**2 + b**2)**0.5  # Calculate c using the Pythagorean theorem

        if c.is_integer() and c <= 50:

            print(f"Pythagorean Triplet: ({a}, {b}, {int(c)})")

Within the loops, the program calculates the value of c using the Pythagorean theorem (c = sqrt(a^2 + b^2)). The is_integer() method is then used to check if c is a whole number. If it is, and if c is less than or equal to 50, the triplet (a, b, c) is printed as a Pythagorean triplet.

# Function to check if a, b, c form a Pythagorean triplet

def is_pythagorean_triplet(a, b, c):

    return a**2 + b**2 == c**2

# Generate and print all Pythagorean triplets with side lengths <= 50

for a in range(1, 51):

    for b in range(a, 51):

        c = (a**2 + b**2)**0.5  # Calculate c using the Pythagorean theorem

        if c.is_integer() and c <= 50:

            print(f"Pythagorean Triplet: ({a}, {b}, {int(c)})")

Rewrite the following program using for loop. lst = ['desert', 'dessert', 'to', 'too', 'lose', 'loose'] s = 'Mumbai' i = 0 while i < len(lst) : if i > 3 : break else : print(i, lst[i], s[i]) i += 1

 Rewrite the following program using for loop.

lst = ['desert', 'dessert', 'to', 'too', 'lose', 'loose']

s = 'Mumbai'

i = 0

while i < len(lst) :

if i > 3 :

break

else :

print(i, lst[i], s[i])

i += 1

Here's the equivalent program using a for loop:

lst = ['desert', 'dessert', 'to', 'too', 'lose', 'loose']

s = 'Mumbai'

for i in range(len(lst)):

    if i > 3:

        break

    else:

        print(i, lst[i], s[i])

In this version, the for loop iterates over the indices of the lst list using range(len(lst)). The if condition inside the loop checks whether i is greater than 3, and if so, it breaks out of the loop. Otherwise, it prints the values of i, lst[i], and s[i]. The loop increment is handled automatically by the for loop construct, eliminating the need for an explicit increment (i += 1).

Write a program to print first 25 odd numbers using range( ).

 You can use the range() function with a step of 2 to generate odd numbers and then use a loop to print the first 25 odd numbers. Here's a simple Python program to achieve this:

# Using range() to generate the first 25 odd numbers

odd_numbers = list(range(1, 50, 2))[:25]

# Printing the first 25 odd numbers

for number in odd_numbers:

    print(number)

In this program:

range(1, 50, 2) generates odd numbers starting from 1, up to, but not including 50, with a step of 2.

[:25] is used to select the first 25 numbers from the list generated by range().

The loop then prints each of the first 25 odd numbers.

a. range(5) b. range(1, 10, 3) c. range(10, 1, -2) d. range(1, 5) e. range(-2)

a. range(5)

b. range(1, 10, 3) 

c. range(10, 1, -2)

d. range(1, 5) 

e. range(-2) 

Let's break down each of the provided ranges:

a. range(5) - This generates a sequence of integers from 0 to 4 (5 is the stopping value, exclusive). So, it produces the numbers 0, 1, 2, 3, and 4.

b. range(1, 10, 3) - This generates a sequence of integers starting from 1, up to, but not including 10, with a step of 3. So, it produces the numbers 1, 4, 7.

c. range(10, 1, -2) - This generates a sequence of integers starting from 10, down to, but not including 1, with a step of -2. So, it produces the numbers 10, 8, 6, 4, 2.

d. range(1, 5) - This generates a sequence of integers starting from 1, up to, but not including 5. So, it produces the numbers 1, 2, 3, 4.

e. range(-2) - This is a bit different. range() requires at least two arguments (start, stop), but here you've provided only one. If you want to generate a range starting from 0 up to, but not including -2, you would need to provide the start and stop values. If you intended to start from 0 and go up to -2, you could use range(0, -2), which would produce the numbers 0, -1.

So, to summarize:

a. 0, 1, 2, 3, 4

b. 1, 4, 7

c. 10, 8, 6, 4, 2

d. 1, 2, 3, 4

e. (Assuming you meant range(0, -2)) 0, -1

Can a do-while loop be used to repeat a set of statements in Python?

 Python does not have a built-in "do-while" loop like some other programming languages do. However, you can achieve similar behavior using a "while" loop with a break statement.

Here's an example of how you can simulate a "do-while" loop in Python:

while True:

    # Code block to be repeated

    # Ask the user if they want to repeat the loop

    user_input = input("Do you want to repeat? (yes/no): ")

    # Check the user's input

    if user_input.lower() != 'yes':

        break  # Exit the loop if the user does not want to repeat

In this example, the loop will continue to execute the code block and prompt the user for input until the user enters something other than "yes." The break statement is used to exit the loop when the desired condition is met.

This pattern achieves the same effect as a "do-while" loop where the loop body is executed at least once before the condition is checked.

Can a while/for loop be used in an if/else and vice versa in Python?

 Yes, it is entirely valid to use loops within conditional statements (if/else) and vice versa in Python. You can nest loops inside if/else statements and if/else statements inside loops based on the requirements of your program.

Here's an example of a while loop inside an if/else statement:

x = 5

if x > 0:

    while x > 0:

        print(x)

        x -= 1

else:

    print("x is not greater than 0")

And here's an example of an if/else statement inside a for loop:

numbers = [1, 2, 3, 4, 5]

for num in numbers:

    if num % 2 == 0:

        print(f"{num} is even")

    else:

        print(f"{num} is odd")

The key is to maintain proper indentation to denote the block of code within the loop or the conditional statement. This helps Python understand the structure of your code.

Can a while loop be nested within a for loop and vice versa?

Yes, both while loops can be nested within for loops and vice versa in Python. Nesting loops means placing one loop inside another. This is a common programming practice when you need to iterate over elements in a nested structure, such as a list of lists or a matrix.

Here's an example of a while loop nested within a for loop:

for i in range(3):

    print(f"Outer loop iteration {i}")

    

    j = 0

    while j < 2:

        print(f"  Inner loop iteration {j}")

        j += 1

And here's an example of a for loop nested within a while loop:

i = 0

while i < 3:

    print(f"Outer loop iteration {i}")

    

    for j in range(2):

        print(f"  Inner loop iteration {j}")

    

    i += 1

In both cases, the indentation is crucial in Python to define the scope of the loops. The inner loop is indented and considered part of the outer loop based on the indentation level.

Can range( ) function be used to generate numbers from 0.1 to 1.0 in steps of 0.1?

 No, the range() function in Python cannot be used directly to generate numbers with non-integer steps. The range() function is designed for generating sequences of integers.

However, you can achieve the desired result using the numpy library, which provides the arange() function to generate sequences of numbers with non-integer steps. Here's an example:

import numpy as np

# Generate numbers from 0.1 to 1.0 with steps of 0.1

numbers = np.arange(0.1, 1.1, 0.1)

print(numbers)

In this example, np.arange(0.1, 1.1, 0.1) generates an array of numbers starting from 0.1, incrementing by 0.1, and stopping before 1.1.

If a = 10, b = 12, c = 0, find the values of the following expressions: a != 6 and b > 5 a == 9 or b < 3 not ( a < 10 ) not ( a > 5 and c ) 5 and c != 8 or c

Questions - 

 If a = 10, b = 12, c = 0, find the values of the following expressions:

a != 6 and b > 5

a == 9 or b < 3

not ( a < 10 )

not ( a > 5 and c )

5 and c != 8 or c

Solution and Explanations 

Let's evaluate each expression using the given values:

a != 6 and b > 5

a != 6 is True (because 10 is not equal to 6).

b > 5 is also True (because 12 is greater than 5).

The and operator returns True only if both expressions are True.

Therefore, the result is True.

a == 9 or b < 3

a == 9 is False (because 10 is not equal to 9).

b < 3 is False (because 12 is not less than 3).

The or operator returns True if at least one expression is True.

Since both expressions are False, the result is False.

not (a < 10)

a < 10 is False (because 10 is not less than 10).

The not operator negates the result, so not False is True.

not (a > 5 and c)

a > 5 is True because 10 is greater than 5.

c is 0.

a > 5 and c evaluates to True and 0, which is False because and returns the first False value encountered.

The not operator negates the result, so not (True and 0) is not False, which is True.

Therefore, the output of the code will be True.

5 and c != 8 or c

5 is considered True in a boolean context.

c != 8 is True (because 0 is not equal to 8).

The and operator returns the last evaluated expression if all are True, so it evaluates to True.

The or operator returns True if at least one expression is True.

Therefore, the result is True.

Python Coding challenge - Day 72 | What is the output of the following Python code?

 

Code - 

j = 1

while j <= 2 :

  print(j)

  j++

Explanation - 

It looks like there's a small syntax error in your code. In Python, the increment operator is +=, not ++. Here's the corrected version:

j = 1

while j <= 2:

    print(j)

    j += 1

This code initializes the variable j with the value 1 and then enters a while loop. The loop continues as long as j is less than or equal to 2. Inside the loop, the current value of j is printed, and then j is incremented by 1 using j += 1.

When you run this corrected code, the output will be:

1

2

Each number is printed on a new line because the print function automatically adds a newline character by default.

a = 10 b = 60 if a and b > 20 : print('Hello') else : print('Hi')

Code - 

a = 10

b = 60

if a and b > 20 :

  print('Hello')

else :

  print('Hi')

Explanation -

The above code checks the condition a and b > 20. In Python, the and operator has a higher precedence than the comparison (>), so the expression is evaluated as (a) and (b > 20).

Here's how it breaks down:

The value of a is 10.

The value of b is 60.

The first part of the condition, a, is considered "truthy" in Python.

The second part of the condition, b > 20, is also true because 60 is greater than 20.

So, both parts of the and condition are true, and the print('Hello') statement will be executed. Therefore, the output of the code will be:

Hello

a = 10 a = not not a print(a)

CODE - 

a = 10

a = not not a

print(a)

Solution - 

In the above code, the variable a is initially assigned the value 10. Then, the line a = not not a is used. The not operator in Python is a logical NOT, which negates the truth value of a boolean expression.

In this case, not a would be equivalent to not 10, and since 10 is considered "truthy" in Python, not 10 would be False. Then, not not a is applied, which is equivalent to applying not twice. So, not not 10 would be equivalent to not False, which is True.

Therefore, after the execution of the code, the value of a would be True, and if you print a, you will get: True

Rewrite the following code in 1 line

 Rewrite the following code in 1 line

x = 3 y = 3.0 if x == y : print('x and y are equal') else : print('x and y are not equal')

In one line

x, y = 3, 3.0

print('x and y are equal') if x == y else print('x and y are not equal')

Explanation -

Initializes two variables, x and y, with the values 3 and 3.0, respectively. Then, it uses a conditional expression (also known as a ternary operator) to check if x is equal to y. If they are equal, it prints 'x and y are equal'; otherwise, it prints 'x and y are not equal'.

In this case, x and y are equal because the values are numerically the same, even though one is an integer (x) and the other is a float (y). The output of the code would be: x and y are equal

msg = 'Aeroplane' ch = msg[-0] print(ch)

msg = 'Aeroplane'

ch = msg[-0]

print(ch)

In Python, indexing starts from 0, so msg[-0] is equivalent to msg[0]. Therefore, ch will be assigned the value 'A', which is the first character of the string 'Aeroplane'. If you run this code, the output will be: A

Step by Step : 

msg = 'Aeroplane': This line initializes a variable msg with the string 'Aeroplane'.

ch = msg[-0]: This line attempts to access the character at index -0 in the string msg. However, in Python, negative indexing is used to access elements from the end of the sequence. Since -0 is equivalent to 0, this is the same as accessing the character at index 0.

print(ch): This line prints the value of the variable ch.

Now, let's evaluate the expression step by step:

msg[-0] is equivalent to msg[0], which accesses the first character of the string 'Aeroplane', so ch is assigned the value 'A'.

Therefore, when you run the code, the output will be : A

Python Coding challenge - Day 71 | What is the output of the following Python code?

 

Questions - 

for index in range(20, 10, -3):

    print(index, end=' ')

Solution - 

range(20, 10, -3): This creates a range of numbers starting from 20, decrementing by 3 at each step, until it reaches a number less than 10. So, the sequence is 20, 17, 14, 11.

for index in range(20, 10, -3):: This is a for loop that iterates over each value in the specified range. In each iteration, the variable index takes on the next value in the range.

print(index, end=' '): This prints the value of index followed by a space. The end=' ' argument is used to specify that a space should be printed at the end of each value instead of the default newline character.

When you run this code, the output will be:

Output :   20 17 14 11
