Python Program: Swap Two Numbers in Python

Here you will get Python program to swap two numbers with and without using the function in Python

Swap Two Numbers in Python without Function

a=10
b=20
print("before swapping\na=", a, " b=", b)

temp = a
a = b
b = temp
print("\nafter swapping\na=", a, " b=", b)

Output :
before swapping a= 10 b= 20

after swapping a= 20 b= 10

Swap Two Numbers in Python using Function

def swap_numbers(num1, num2):
    temp = num1
    num1 = num2
    num2 = temp
    return num1, num2

# Prompt the user to enter the first number
num1 = int(input("Enter the first number: "))

# Prompt the user to enter the second number
num2 = int(input("Enter the second number: "))

# Call the function to swap the numbers
num1, num2 = swap_numbers(num1, num2)

# Print the swapped values
print("After swapping:")
print("First number:", num1)
print("Second number:", num2)

Output :

After swapping:

First number: 5

Second number: 3

In this code, we define a function called swap_numbers that takes two arguments, num1 and num2. The function swaps the values of the two numbers using a temporary variable temp and returns the swapped values.

After prompting the user to enter the two numbers, we call the swap_numbers function with the input values. The function returns the swapped values, which we then assign to num1 and num2. Finally, we print the swapped values on the console.
