Learn to write pattern-based programs in Python to reverse numbers and understand the logic behind it

beginner Published 2 Apr 2026
Action Steps
  1. Write a Python program to reverse a number using a while loop
  2. Initialize variables to store the reversed number and the input number
  3. Use the modulo operator to extract the last digit of the input number and append it to the reversed number
  4. Update the input number by removing the last digit
  5. Repeat the process until the input number becomes 0
  6. Test the program with different input numbers to verify its correctness
