Why is it not same in Python?

 

Explanation:

a = 0.2 + 0.4:

This line adds 0.2 and 0.4, resulting in 0.6.

However, due to floating-point precision limitations in computers, the actual value stored in a might be slightly different from the exact mathematical value of 0.6.

b = 0.6:

This line assigns the value 0.6 directly to b.

print(a == b):

This line compares the values of a and b. Since the values might differ slightly due to floating-point precision, the comparison evaluates to False.

a = 0.1 + 0.3:

This line adds 0.1 and 0.3, resulting in 0.4.

Again, due to floating-point precision, the actual value stored in a might be slightly different from the exact mathematical value of 0.4.

b = 0.4:

This line assigns the value 0.4 directly to b.

print(a == b):

This line compares the values of a and b. In this case, the values might be close enough within the floating-point precision, so the comparison evaluates to True.

Key Points:

Floating-point numbers are represented in binary format with limited precision, which can lead to slight inaccuracies when performing arithmetic operations.

Comparing floating-point numbers for exact equality can be unreliable due to these precision limitations.

If you need to compare floating-point numbers for equality, it's often better to check if they are within a certain tolerance range rather than expecting exact equality.

Careful with chained operations

 

Let's break down the expressions one by one:

1. (False == False) in [False]

(False == False): This evaluates to True, because False is equal to False.

True in [False]: Now the expression becomes True in [False]. This checks if True is in the list [False].

The result is False because the list only contains False, not True.

So, the overall result of (False == False) in [False] is False.

2. False == (False in [False])

(False in [False]): This checks if False is in the list [False].

This is True because False is indeed in [False].

False == True: Now the expression becomes False == True.

This is False because False is not equal to True.

So, the overall result of False == (False in [False]) is False.

3. False == False in [False]

This is a chained comparison, equivalent to:

(False == False) and (False in [False])

False == False: This is True because False is equal to False.

False in [False]: This is True because False is in the list [False].

So, the overall result of False == False in [False] is True.

Summary of Results:

(False == False) in [False]: False

False == (False in [False]): False

False == False in [False]: True

Each expression behaves differently based on how the logical comparisons and list membership are evaluated.

A Quick Guide to Learning Python: Easy Coding, Designed for Beginners | Free

 

Mastering a programming language requires understanding code and writing it effectively. This book offers quizzes to improve skills in reading and understanding code, while the exercises aim to improve writing code skills.

Each chapter starts with an explanation and code examples and is followed by exercises and quizzes, offering an opportunity for self-testing and understanding which level you achieved.

This book goes beyond the traditional approach by explaining Python syntaxes with real-world code examples. This approach makes learning exciting and ensures readers can apply their knowledge effectively. The included exercises and quizzes, along with their solutions, provide a guarantee to readers and empower them to create simple yet valuable programs.

Learning one computer language facilitates learning other computer languages. This principle arises from rules and logic that connect computer languages. A confirmation of this was when I was asked to teach the C# programming language at the University of Applied Science. Despite having no experience with C#, I dedicated a weekend to diving into the language and realized it wasn't fundamentally different from other object-oriented programming languages.

Python is also a language reliant on object-oriented programming principles. Our focus is real-world examples, enabling you to apply these concepts in your programming works. Learning programming is a communication tool with computers, as machines operate using their language defined by specific logical structures and sentences known as statements.

Python Coding challenge - Day 244 | What is the output of the following Python Code?

 

In this code snippet:

s = 'clcoding'

index = s.find('z')

print(index)

s = 'clcoding': This assigns the string 'clcoding' to the variable s.

s.find('z'): The .find() method is used to search for the first occurrence of the specified substring 'z' in the string s. If the substring is found, it returns the index (position) of its first occurrence. If the substring is not found, .find() returns -1.

Since 'z' is not in the string 'clcoding', s.find('z') will return -1.

print(index): This prints the value of index, which in this case is -1.

Output:  -1

Python Coding challenge - Day 243 | What is the output of the following Python Code?

 

Code:

s = 'clcoding.com'

index = s.find('com')

print(index)

Solution and Explanation: 

Explanation:

s = 'clcoding.com':

This defines a string variable s with the value 'clcoding.com'.

index = s.find('com'):

The find() method searches for the substring 'com' in the string s.

It returns the index of the first character of the first occurrence of the substring.

If the substring is not found, find() returns -1.

In this case, 'com' is present in 'clcoding.com', and it starts at index 9.

print(index):

This prints the value of index, which is 9.

String Breakdown:

The string 'clcoding.com' has characters at the following positions:

Index:  0 1 2 3 4 5 6 7 8 9 10 11

Chars:  c l c o d i n g . c  o  m

Here, the substring 'com' starts at index 9.

Output: 9

The find() method is useful for locating substrings within a string. In this case, it returns the index where 'com' begins.

4 Python Power Moves to Impress Your Colleagues

 

1. Use List Comprehensions for Cleaner Code

List comprehensions are a compact way to generate lists from existing lists or other iterable objects. They are often faster and more readable than traditional for loops.

# Traditional for loop approach

squares = []

for i in range(10):

    squares.append(i**2)

# List comprehension approach

squares = [i**2 for i in range(10)]

2. Use the zip() Function for Iterating Over Multiple Lists

The zip() function allows you to combine multiple iterables and iterate through them in parallel. This is useful when you need to handle multiple lists in a single loop.

names = ['Alice', 'Bob', 'Charlie']

scores = [85, 90, 95]

for name, score in zip(names, scores):

    print(f'{name}: {score}')

Alice: 85

Bob: 90

Charlie: 95

3. Use enumerate() for Indexed Loops

Instead of manually managing an index variable while iterating, you can use the enumerate() function, which provides both the index and the value from an iterable.

fruits = ['apple', 'banana', 'cherry']

# Without enumerate

for i in range(len(fruits)):

    print(i, fruits[i])

# With enumerate

for i, fruit in enumerate(fruits):

    print(i, fruit)

0 apple

1 banana

2 cherry

0 apple

1 banana

2 cherry

4. Use Unpacking for Cleaner Variable Assignment

Python supports unpacking, which allows you to assign multiple variables in a single line. This is particularly useful when working with tuples or lists.

# Unpacking a tuple

point = (3, 5)

x, y = point

print(f'X: {x}, Y: {y}')

# Unpacking with a star operator

a, *b, c = [1, 2, 3, 4, 5]

print(a, b, c)  

X: 3, Y: 5

1 [2, 3, 4] 5
