Python Coding challenge - Day 122 | What is the output of the following Python Code?

 


Code: 

age = 5
if True:
    age = 6
print(age)


Solution and Explanation: 

age = 5: This line initializes a variable named age and assigns it the value 5.

if True:: This line begins an if statement with the condition True. Since True is always true, the code block following this line will always be executed.

Inside the if block:
age = 6
This line updates the value of the age variable to 6. This happens because the code inside the if block is executed when the condition is true.

print(age): This line prints the current value of the age variable. Since the if block was executed, and the value of age was set to 6 within that block, the output of this print statement will be 6.

So, the output of the code will be:

6

5 ways to swap two numbers in Python

 



# 5 ways to swap two numbers in Python

# 1. Using a Temporary Variable:

a = 5
b = 10

temp = a
a = b
b = temp

print("After swapping: a =", a, ", b =", b)

#clcoding.com

# 2. Without Using a Temporary Variable :

a = 5
b = 10

a = a + b
b = a - b
a = a - b

print("After swapping: a =", a, ", b =", b)

#clcoding.com

# 3. Using Tuple Unpacking:

a = 5
b = 10

a, b = b, a

print("After swapping: a =", a, ", b =", b)

#clcoding.com

# 4. Using XOR bitwise operation:

a = 5
b = 10

a = a ^ b
b = a ^ b
a = a ^ b

print("After swapping: a =", a, ", b =", b)

#clcoding.com

# 5. Using Arithmetic Operators in a Single Line:

a = 5
b = 10

a, b = b, a + b - a

print("After swapping: a =", a, ", b =", b)

#clcoding.com


Python Coding challenge - Day 121 | What is the output of the following Python Code?

 

The provided code defines a function called calc that takes a variable number of arguments using the *args syntax. The function calculates the product of the number of arguments and the last argument in the given sequence. Let's break down the code:

def calc(*args):
    count = len(args)
    elem = args[count - 1]
    return count * elem

print(calc(2, 2, 1, 3))

Here's how the function works:

*args in the function definition allows the function to accept any number of arguments. All the arguments passed to the function are collected into a tuple named args.

count is assigned the length of the args tuple, which gives the number of arguments passed to the function.

elem is assigned the value of the last element in the args tuple (i.e., args[count - 1]).

The function returns the product of count and elem.

The print(calc(2, 2, 1, 3)) statement calls the calc function with the arguments 2, 2, 1, 3.

Now, let's substitute the values:

count is 4 (number of arguments).

elem is 3 (the last argument).

The function returns count * elem, which is 4 * 3 = 12.

Therefore, the final result printed by print(calc(2, 2, 1, 3)) is 12.

Python Coding challenge - Day 120 | What is the output of the following Python Code?

 


Code :

def sum(num):
    if num == 1:
        return 1
    return num + sum(num - 1)
print(sum(5))


Solution and Explanation:


Here's how the function works:

The function sum takes a parameter num.
The base case is defined with if num == 1:. If num is 1, the function returns 1.
If the base case is not met, the function returns num + sum(num - 1). This is the recursive step, where the sum of the current num and the sum of the numbers from 1 to num - 1 is calculated.
The print(sum(5)) statement calls the sum function with the argument 5 and prints the result.
Let's trace the function call for sum(5):

sum(5) returns 5 + sum(4)
sum(4) returns 4 + sum(3)
sum(3) returns 3 + sum(2)
sum(2) returns 2 + sum(1)
sum(1) returns 1 (base case)
Now we substitute these values back:

sum(2) returns 2 + 1 = 3
sum(3) returns 3 + 3 = 6
sum(4) returns 4 + 6 = 10
sum(5) returns 5 + 10 = 15
So, the final result printed by print(sum(5)) is 15.

Python Coding challenge - Day 119 | What is the output of the following Python Code?

 

Code: 

value = 7 and 8

result = "Even" if value % 2 == 0 else "Odd"

print(result)

Solution and Explanation: 

The variable value is assigned the result of the logical AND operation between 7 and 8. In Python, the and operator returns the last true value or the first false value. In this case, since both 7 and 8 are considered true in a boolean context, value will be assigned the last true value, which is 8.

Then, the code checks if value % 2 == 0 (i.e., if value is even) and assigns "Even" to result if true, otherwise "Odd". Since 8 is even, the output of the code will be:

Even

Python for Data Analysts and Scientists: Jump start your career in Data Analysis and Data Science Field

 


This is an excellent book for those who want to Jumpstart their career in Data Analytics and Data Scientist field.

My interest in learning Python script faced a challenging question - “Where shall I start from?”. I browsed through numerous online videos and training materials but with little success. After I agreed to pay a reasonable amount, a training course from a well-known e-learning platform gave me introductory knowledge on Python script. Learning the basic Python commands is one thing, whereas applying them to real life problems is another. For many months, the question - “Which Python commands are important in solving real-life problems?” bothered me a lot. It took me several sleepless nights, and a frantic lookout for a concise list of Python commands from an ocean of online information. My hands-on experiences designing Machine Learning models, performing root cause analysis by statistical hypothesis, and providing consultation as a Data Scientist, helped me learn the most crucial Python commands. The birth of this book is from the thoughts of my struggle in mastering and applying the Python script for resolving numerous challenging tasks. This book concisely lists the essential commands, the data visualization technics, and the statistical knowledge. I have mindfully placed the contents of this book for the day-to-day activities of a Data Analyst and a Data Scientist. This book aims to provide a quick starting platform for those who want to dive into the vast field of Machine Learning and Data Analytics. Further, this book will be a quick reference for those already in this field. With the hope of helping beginners and practitioners, and with a silent prayer of goodwill, I walk you through the simple steps to the proficiency in Python. Let us dive in and enjoy the journey into the world of Python.

What Python Developers Say About The Book:

“Go forth and learn this amazing language using this great book.” — Michael Kennedy, Talk Python

“The wording is casual, easy to understand, and makes the information flow well.” — Thomas Wong, Pythonista

“I floundered for a long time trying to teach myself. I slogged through dozens of incomplete online tutorials. I snoozed through hours of boring screencasts. I gave up on countless crufty books from big-time publishers. And then I found Real Python. The easy-to-follow, step-by-step instructions break the big concepts down into bite-sized chunks written in plain English. The authors never forget their audience and are consistently thorough and detailed in their explanations. I’m up and running now, but I constantly refer to the material for guidance.” — Jared Nielsen, Pythonista
