Python Program To Check Palindrome Number

Chapter: Python Last Updated: 12-03-2023 13:32:33 UTC


            /* ............... START ............... */
# Function to check if a number is palindrome or not
def is_palindrome(num):
    # Convert the number to a string
    num_str = str(num)
    # Reverse the string
    reversed_str = num_str[::-1]
    # Check if the reversed string is equal to the original string
    if num_str == reversed_str:
        return True
        return False

# Take input from the user
num = int(input("Enter a number: "))

# Check if the number is a palindrome or not
if is_palindrome(num):
    print(num, "is a palindrome")
    print(num, "is not a palindrome")

                /* ............... END ............... */


Enter a number: 121
121 is a palindrome

Enter a number: 123
123 is not a palindrome


  • Define a function called is_palindrome() that takes a number as an argument and returns True if the number is a palindrome or False if it is not.
  • Convert the number to a string using the str() function and assign the resulting string to the variable num_str.
  • Create a reversed version of the string by slicing it with the notation [::-1], which means "start at the end, move to the beginning, and step backwards one character at a time". Assign the resulting reversed string to the variable reversed_str.
  • Check if num_str (the original string) is equal to reversed_str (the reversed string). If they are equal, return True. If they are not equal, return False.
  • Prompt the user to enter a number using the input() function and convert the user's input to an integer using the int() function. Assign the resulting integer to the variable num.
  • Call the is_palindrome() function with the argument num.
  • If the function returns True, print a message saying that the number is a palindrome.
  • If the function returns False, print a message saying that the number is not a palindrome.
