Python program to check if a number or string a palindrome or not

Given a string or an integer,Write a python program to check if a string or an integer is a palindrome.

Palindrome

A given string or a number is said to be palindrome if the opposite or the reverse of the string or a number is same as the orginal string or number.

Example:

1. 12321 - Palindrome

2. 345 - Not Palindrome

3. SOS - Palindrome

4. RUN - Not Palindrome

Python Program

#Function if the given input is a string

def palinStr(n):

    #check if the reverse of a string is equal to the original string

    print('Palindrome') if n == n[::-1] else print('Not a palindrome')

#Function if the given input is a number

def palinInt(n):

    rem = 0

    temp = n

    while n>0:

        #Taking the last number

        dig = n%10

        #reverse the number from last digit to first digit

        rem = rem*10+dig

        n = n//10

    #check if the reverse of a string is equal to the original string

    print("Palindrome") if temp == rem else print("Not a palindrome")

#Taking user input

n = input()

#calling the function base on the user input, A string or a number

palinInt(int(n)) if n.isnumeric() else palinStr(n)

Input:

12321

Output:

Palindrome

Input:

RUN

Output:

Not a palindrome
