Lecture 11:- Swap Two Variables in Python

You can swap the values of two variables in Python using a temporary variable or by using tuple unpacking. Here are two common methods to swap variables:

1. Using a Temporary Variable:

pythonCopy code

# Method 1: Using a temporary variable a = 5 b = 10 # Swapping values temp = a a = b b = temp print("a =", a)  # Output: a = 10 print("b =", b)  # Output: b = 5

1. Using Tuple Unpacking:

pythonCopy code

# Method 2: Using tuple unpacking a = 5 b = 10 # Swapping values a, b = b, a print("a =", a)  # Output: a = 10 print("b =", b)  # Output: b = 5

In the second method, (b, a) creates a tuple with the values of b and a, and then tuple unpacking is used to assign the elements of the tuple back to a and b, effectively swapping their values.

Both methods achieve the same result, but tuple unpacking is more concise and commonly used in Python for swapping variables. It's a neat and efficient way to exchange the values of two variables without needing a temporary variable.
