In this video, we’ll learn how to swap the values of two variables in Python without using a third variable. This is a quick and efficient way to swap variables in just one line.

Initialize two variables
a = 5
b = 10

Swap the values
a, b = b, a

Display the result
print("After swapping:")
print("a =", a)
print("b =", b)

Explanation:

Variable Initialization: We start by defining two variables, a and b, with values 5 and 10, respectively.

Swapping Without a Third Variable: The line a, b = b, a uses Python’s multiple assignment feature to swap the values in one line. Here’s how it works:

b (which is 10) is assigned to a.
Simultaneously, a (which is 5) is assigned to b.
This technique efficiently swaps the variables without needing an extra temporary variable.
Displaying the Swapped Values: Finally, we print the new values of a and b to confirm that the swap was successful.

Output
After swapping:
a = 10
b = 5
