## Python program to find the reverse of a given number

Write a Python program to accept a number from the user, find and display the reverse of a given number.

## Video Tutorial

Example:

Let the user has entered the number 123. Then the procedure to find the reverse of a number is given below.

num = 123 rev = 0

Iteration 1

rem = num % 10 = 123 % 10 = 3

rev = rev * 10 + rem = 3

num = num //10 = 123 // 10 = 12

Iteration 2

rem = num % 10 = 12 % 10 = 2

rev = rev * 10 + rem = 30 + 2 = 32

num = num //10 = 12 // 10 = 1

Iteration 3

rem = num % 10 = 1 % 10 = 1

rev = rev * 10 + rem = 320 + 1 = 321

num = num //10 = 1 // 10 = 0

### Source code of Python program to find the reverse of a given number

```num = int (input("Enter the number: "))
org = num
rev = 0
while num > 0:
rem = num % 10
rev = rev * 10 + rem
num = num // 10

print ("The rverse of ", org, "is ", rev)```

### Output:

Case 1:

Enter the number: 321

The rverse of 321 is 123

Case 2:

Enter the number: 1234321

The rverse of 1234321 is 1234321
