what is the difference between display( ) and show( )?

 

display( ) is an object method as it receives the address of the object

(inself) using which it is called. show( ) is class method and it can be

called independent of an object.

In the given code snippet, display() is a method of a class (Message), and show() is a standalone function. The key difference lies in their usage and the context in which they are defined.

display(self, msg):

This is a method of a class named Message.

The method takes two parameters: self (a reference to the instance of the class) and msg (another parameter).

The display() method is intended to be called on an instance of the Message class, and it can access and manipulate the attributes of that instance.

Example:

# Creating an instance of the Message class

my_message = Message()

# Calling the display method on the instance

my_message.display("Hello, World!")

show(msg):

This is a standalone function that is not part of any class.

It takes a single parameter, msg.

The show() function is not associated with any specific instance of a class and does not have access to instance-specific attributes.

Example:

# Calling the show function without an instance

show("Hello, World!")

In summary, the display() method is associated with instances of the Message class and can be called on those instances, while the show() function is standalone and can be called without creating an instance of any class. The distinction between methods and standalone functions is an essential concept in object-oriented programming.

Python Coding challenge - Day 107 | What is the output of the following Python Code?

 

The output of the code will be 48.

Here's a breakdown of how the code works:

Function Definition:

The code defines a recursive function named fun that takes two integer arguments, x and y.

Base Case:

If x is equal to 0, the function returns y. This is the base case that stops the recursion.

Recursive Case:

If x is not 0, the function calls itself recursively with the arguments x - 1 and x * y. This means the function keeps calling itself with updated values until it reaches the base case.

Function Call and Output:

The code calls the fun function with the arguments 4 and 2: print(fun(4, 2)).

This initiates the recursive process, which unfolds as follows:

fun(4, 2) calls fun(3, 8) because 4 is not 0.

fun(3, 8) calls fun(2, 24).

fun(2, 24) calls fun(1, 48).

fun(1, 48) calls fun(0, 48).

Finally, fun(0, 48) returns 48 because x is now 0 (the base case is reached).

This value, 48, is then printed to the console, resulting in the output you see.

In essence, the code calculates a product of numbers in a recursive manner, with the final product being 2 * 4 * 3 * 2 = 48.

Python Coding challenge - Day 106 | What is the output of the following Python Code?

 

The above code  uses the filter function along with a lambda function to filter out elements from the list lst based on a condition. In this case, it filters out elements that have a length less than 8. Here's a breakdown of the code:

lst = ['Python', 'Clcoding', 'Intagram']

lst1 = filter(lambda x: len(x) >= 8, lst)

print(list(lst1))

lambda x: len(x) >= 8: This lambda function checks if the length of the input string x is greater than or equal to 8.

filter(lambda x: len(x) >= 8, lst): The filter function applies the lambda function to each element of the list lst. It retains only those elements for which the lambda function returns True.

list(lst1): Converts the filtered result into a list.

print(list(lst1)): Prints the final filtered list.

In this specific example, the output would be:

['Clcoding', 'Intagram']

This is because only the elements 'Clcoding' and 'Intagram' have lengths greater than or equal to 8.

Python Coding challenge - Day 105 | What is the output of the following Python Code?

 

The given code creates a set s using a set comprehension to check if each element in the list lst is even (True) or not (False). The condition n % 2 == 0 is used to determine if an element is even. Here's the code and its output:

lst = [2, 7, 8, 6, 5, 5, 4, 4, 8]

s = {True if n % 2 == 0 else False for n in lst}

print(s)

Output:

{False, True}

In this case, the set s contains both True and False because there are even and odd numbers in the list. The set comprehension creates a set of unique values based on the condition specified.

Using comprehension how will you convert

 

Using comprehension how will you convert

{'a' : 1, 'b' : 2, 'c' : 3, 'd' : 4, 'e' : 5}

into

{'A' : 100, 'B' : 200, 'C' : 300, 'D' : 400, 'E' : 500}?

Output

d = {'a' : 1, 'b' : 2, 'c' : 3, 'd' : 4, 'e' : 5}

d = {key.upper( ) : value * 100 for (key, value) in d.items( )}

print(d)

Another Method : 

original_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}

converted_dict = {key.upper(): value * 100 for key, value in original_dict.items()}

print(converted_dict)

The upper() method is used to convert the keys to uppercase, and the values are multiplied by 100. The resulting dictionary is {'A': 100, 'B': 200, 'C': 300, 'D': 400, 'E': 500}.

Python Coding challenge - Day 104 | What is the output of the following Python Code?

 

print(max(min(False, False), 1, True))

1

Explanation:

The min function returns the smallest value among its arguments. Since False is considered 0 in Python, the min of False and False is still False. Then, the max function returns the largest value among False, 1, and True. Since True is equivalent to 1 in Python and 1 is greater than 0, the max function returns 1.

Read More

Python Coding challenge - Day 103 | What is the output of the following Python Code?

 

Code : 

print(min(max(False,-3,-4), 2,7))

Let's break down the expression step by step:

max(False, -3, -4): This evaluates to False because False is treated as 0 in numerical comparisons, and 0 is not greater than -3 or -4.

min(False, 2, 7): This evaluates to False because False is treated as 0 in numerical comparisons, and 0 is the minimum among False, 2, and 7.

So, the output of the expression will be False.

Python Coding challenge - Day 102 | What is the output of the following Python Code?

 

Code :

my_tuple = (5, 12, 19, 3, 25)

tup = my_tuple[-2::-2] 

print(tup)

Let's break down the code:

Sure! The output of the code is:

(3, 12)

Explanation:

You created a tuple named my_tuple with five elements: 5, 12, 19, 3, and 25.

Then, you created another tuple named tup by slicing my_tuple from the second-last element (-2) to the first element (-1) with a step size of -2 (meaning you iterate from the second-last element to the first element, reversing the order every two elements).

Finally, you printed the tup tuple, which contains the elements extracted from my_tuple: (3, 12).

Python Coding challenge - Day 101| What is the output of the following Python Code?

 

Code :

numbers = [12, 5, 8, 13, 4]

Num = numbers[::2]  

print(Num)

Solution and Explanation: 

The expression numbers[::2] is a slicing operation with the following parameters:

The starting index is omitted, so it starts from the beginning of the list.

The stopping index is omitted, so it goes until the end of the list.

The step is 2, which means it selects every second element.

So, numbers[::2] will select elements from the original list with a step of 2. Let's break it down:

Element at index 0: 12

Element at index 2: 8

Element at index 4: 4

Therefore, the result will be a new list containing the elements [12, 8, 4]. When you print the result, you'll get:

[12, 8, 4]

This course can also be taken for academic credit as ECEA 5385, part of CU Boulder’s Master of Science in Electrical Engineering degree.

Developing tomorrow's industrial infrastructure is a significant challenge. This course goes beyond the hype of consumer IoT to emphasize a much greater space for potential embedded system applications and growth: The Industrial Internet of Things (IIoT), also known as Industry 4.0. Cisco’s CEO stated: “IoT overall is a $19 Trillion market. IIoT is a significant subset including digital oilfield, advanced manufacturing, power grid automation, and smart cities”.

This is part 1 of the specialization. The primary objective of this specialization is to closely examine emerging markets, technology trends, applications and skills required by engineering students, or working engineers, exploring career opportunities in the IIoT space. The structure of the course is intentionally wide and shallow: We will cover many topics, but will not go extremely deep into any one topic area, thereby providing a broad overview of the immense landscape of IIoT. There is one exception: We will study security in some depth as this is the most important topic for all "Internet of Things" product development.

In this course students will learn :

  * What Industry 4.0 is and what factors have enabled the IIoT

  * Key skills to develop to be employed in the IIoT space

  * What platforms are, and also market information on Software and Services

  * What the top application areas are (examples include manufacturing and oil & gas)

Join Free:Launching Machine Learning: Delivering Operational Success with Gold Standard ML Leadership

There are 4 modules in this course

Machine learning runs the world. It generates predictions for each individual customer, employee, voter, and suspect, and these predictions drive millions of business decisions more effectively, determining whom to call, mail, approve, test, diagnose, warn, investigate, incarcerate, set up on a date, or medicate. 

But, to make this work, you've got to bridge what is a prevalent gap between business leadership and technical know-how. Launching machine learning is as much a management endeavor as a technical one. Its success relies on a very particular business leadership practice. This means that two different species must cooperate in harmony: the business leader and the quant. 

This course will guide you to lead or participate in the end-to-end implementation of machine learning (aka predictive analytics). Unlike most machine learning courses, it prepares you to avoid the most common management mistake that derails machine learning projects: jumping straight into the number crunching before establishing and planning for a path to operational deployment.

Whether you'll participate on the business or tech side of a machine learning project, this course delivers essential, pertinent know-how. You'll learn the business-level fundamentals needed to ensure the core technology works within - and successfully produces value for - business operations. If you're more a quant than a business leader, you'll find this is a rare opportunity to ramp up on the business side, since technical ML trainings don't usually go there. But know this: The soft skills are often the hard ones.

After this course, you will be able to:

- Apply ML: Identify the opportunities where machine learning can improve marketing, sales, financial credit scoring, insurance, fraud detection, and much more.

- Plan ML: Determine the way in which machine learning will be operationally integrated and deployed, and the staffing and data requirements to get there. 

- Greenlight ML: Forecast the effectiveness of a machine learning project and then internally sell it, gaining buy-in from your colleagues.

- Lead ML: Manage a machine learning project, from the generation of predictive models to their launch.

- Prep data for ML: Oversee the data preparation, which is directly informed by business priorities.

- Evaluate ML: Report on the performance of predictive models in business terms, such as profit and ROI.

- Regulate ML: Manage ethical pitfalls, such as when predictive models reveal sensitive information about individuals, including whether they're pregnant, will quit their job, or may be arrested - aka AI ethics.

NO HANDS-ON AND NO HEAVY MATH. Rather than a hands-on training, this course serves both business leaders and burgeoning data scientists alike by contextualizing the core technology, guiding you on the end-to-end process required to successfully deploy a predictive model so that it delivers a business impact. There are no exercises involving coding or the use of machine learning software.

WHO IT'S FOR. This concentrated entry-level program is for anyone who wishes to participate in the commercial deployment of machine learning, no matter whether you'll do so in the role of enterprise leader or quant. This includes business professionals and decision makers of all kinds, such as executives, directors, line of business managers, and consultants - as well as data scientists.

LIKE A UNIVERSITY COURSE. This course is also a good fit for college students, or for those planning for or currently enrolled in an MBA program. The breadth and depth of the overall three-course specialization is equivalent to one full-semester MBA or graduate-level course.

IN-DEPTH YET ACCESSIBLE. Brought to you by industry leader Eric Siegel - a winner of teaching awards when he was a professor at Columbia University - this curriculum stands out as one of the most thorough, engaging, and surprisingly accessible on the subject of machine learning. 

VENDOR-NEUTRAL. This specialization includes illuminating software demos of machine learning in action using SAS products. However, the curriculum is vendor-neutral and universally-applicable. The contents and learning objectives apply, regardless of which machine learning software tools you end up choosing to work with. 

PREREQUISITES. Before this course, learners should take the first of this specialization's three courses, "The Power of Machine Learning: Boost Business, Accumulate Clicks, Fight Fraud, and Deny Deadbeats."

Python Coding challenge - Day 100 | What is the output of the following Python Code?

 

Code :

def fun(a, *args, s = '!') :

    print(a, s)

    for i in args :

        print(i, s)

fun(100)

Solution and Explanation:

Function Definition:

def fun(a, *args, s = '!') :

def fun(..): Defines a function named fun.

a: A required positional argument.

*args: A special syntax to accept an arbitrary number of additional positional arguments, gathered as a tuple within the function.

s = '!': An optional keyword argument with a default value of '!'.

Function Body:

  print(a, s)

  for i in args :

    print(i, s)

print(a, s): Prints the value of a followed by the value of s.

for i in args :: Iterates through each argument in the args tuple.

print(i, s): Prints each argument from args followed by the value of s.

Function Call:

fun(100)

Calls the fun function with a single argument, 100.

Output:

100 !

Explanation:

The function call fun(100) assigns 100 to a.

Since no additional positional arguments are provided, args remains an empty tuple.

The first print statement outputs "100 !".

The for loop doesn't execute because args is empty.

Create font art using python - Merry Christmas

 

Free Code :

from colorama import Fore

import pyfiglet

font = pyfiglet.figlet_format('Merry Christmas ')

print(Fore.GREEN+font)

#clcoding.com

Let's break down the code step by step:

Importing Libraries:

from colorama import Fore

import pyfiglet

The colorama library is used for adding color to the output text in the console.

The pyfiglet library is used for creating ASCII art text.

Creating ASCII Art:

font = pyfiglet.figlet_format('Merry Christmas ')

The pyfiglet.figlet_format function is used to convert the text "Merry Christmas" into ASCII art format using a specific font. In this case, it uses the default font.

Printing in Green:

print(Fore.GREEN + font)

Fore.GREEN sets the text color to green using Colorama.

font contains the ASCII art text generated by PyFiglet.

The print statement then outputs the combined result, which is the ASCII art text in green.

To run this code, you'll need to have the colorama and pyfiglet libraries installed. You can install them using the following commands:

pip install colorama

pip install pyfiglet

After installing the required libraries, you can run the script to see the "Merry Christmas" message in green ASCII art in your terminal.
