Hello folks, welcome back to programminginpython.com. Here in this post, I will share a simple Python program that checks whether a number is a palindrome or not. Let’s code a simple program to check palindrome in Python.
Generally, a number is said to be a palindrome number if its reverse is the same as the original number.
For Example, 121 is a palindrome as its reverse is also 121 whereas, 231 is not a palindrome as its reverse is 132.

Palindrome number – Code Visualization
Task :
To check whether a number is a palindrome or not
Approach :
- Read an input number using
input()orraw_input(). - Check whether the value entered is an integer or not.
- We convert that integer number to a string
str(num). - Now we use advanced slice operation
[start:end:step]leaving thestartandendempty and givingstepa value of -1, this slice operation reverses the string. - Now check whether the reverse is equal to num,
- If
reverseis equal tonum, the number is a palindrome - When
reverseis not equal tonum, it is not a palindrome
Program :
num = input('Enter any number : ')
try:
val = int(num)
if num == str(num)[::-1]:
print('The given number is PALINDROME')
else:
print('The given number is NOT a palindrome')
except ValueError:
print("That's not a valid number, Try Again !")
