Here is a simple program to find the reverse of an entered number. Please note that this program works for only positive integers.

#### Source Code:

```
x = input("Please Enter a number to reverse: ")
reverse = 0
while(x):
reverse = reverse * 10
reverse = reverse + x % 10
x = x/10
print(reverse)
```

#### Output:

Please Enter a number to reverse: 12345 54321

### Explaination of the logic

In the above given program, we get the reversed number in the

*reverse*variable (initialized to 0) after completing the while loop.
we add the last digit of the number with

*reverse*variable each time in the loop then we get rid of the last digit by diving it with 10.
Let's see the value of

*reverse variable*after each iteration for an example input, say 12345
