📺 Python Tutorial: How to Swap Variables in One Line of Code using Tuple Unpacking

This video covers:

• ✔️ Exchange the values of two variables using a single line of code.

Problem Statement

Write a Python function called swap_variables that takes two variables, a and b, as input. The function should swap the values of these two variables using the one-line tuple unpacking technique and then return the new values of a and b as a tuple.

Input:

Two variables of any data type. For example:

x = 10
y = 5

Expected Output:

A tuple containing the swapped values. For the example input above:

(5, 10)

Here’s a starting point for the function:

def swap_variables(a, b):
    # Write your one-line swap using tuple unpacking here
    return a, b

# Example usage:
x = 10
y = 5
swapped_x, swapped_y = swap_variables(x, y)
print(f"Original x: {x}, y: {y}")
print(f"Swapped x: {swapped_x}, y: {swapped_y}")
