Method 7: Swap using function (return tuple) Program Code

# Method 7: Using function to swap values
def swap(a, b):
    """Swap two numbers and return swapped values"""
    return b, a

# Main program
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

print(f"\nBefore swap: a = {a}, b = {b}")

# Call swap function
a, b = swap(a, b)

print(f"After swap: a = {a}, b = {b}")
