Reverse a number using Python

In this tutorial we will be knowing how to reverse a given number using Python.

First, let us take a variable and assign a any number with multiple digits to it.

Eg: num=12345

then take another variable, rev_num and assign [0] to it.

E.g. rev_num=0

then take a while loop to perform next step.

E.g: while num!=0

Now, the complete code is here.

num=12345
rev_num=0
while num!=0:
  digit=num%10
  rev_num=rev_num*10+digit
  num//=10
print(str(rev_num))

output:
