Python Program to Reverse a Number

Example 1: Reverse a Number using a while loop

 num = 1234

reversed_num = 0

while num != 0:

    digit = num % 10

    reversed_num = reversed_num * 10 + digit

    num //= 10

print("Reversed Number: " + str(reversed_num))

Example 2: Using String slicing

num = 123456

print(str(num)[::-1])
