Program to reverse a number in Python

Lets write a program to reverse a number in python using for loop.

 

The program to reverse a given number in python is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

number = int(input("Enter number: "))
temp = str(number)
new_num = 0

for i in range(len(temp)):
    last_bit = number % 10
    new_num = (new_num * 10) + last_bit
    number = number // 10

print("The reversed is:",new_num)

The output of the program to reverse a given number in python is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py                         En
Enter number: 12345
The reversed is: 54321

Few important tips about the program

1. We take a user input and make it of integer type. We keep a clone of it in the string format, to evaluate the length of the number.

2. We divide the number by 10, get the remainder and create a new number, multiplying it by 10 and reversing the index positions.

3. Lastly, we reduce the number by dividing it by 10.
