Write a recursive function def isPalindrome(string) that returns True if string is a palindrome, that is, a word that is the same when reversed. Examples of palindromes are “deed”, “rotor”, or “aibohphobia”. Hint: A word is a palindrome if the first and last letters match and the remainder is also a palindrome.

Question

Write the functions with the following headers:

# Return the reversal of an integer, e.g. reverse(456) returns
# 654
def reverse(number):

# Return true if number is a palindrome
def isPalindrome(number):

Use the reverse function to implement isPalindrome. A number is a palindrome if its reversal is the same as itself. Write a test program that prompts the user to enter an integer and reports whether the integer is a palindrome.

Solution

Verified

def reverse(num):
    '''Takes a positive int num, returns the int with reversed digits'''
    stringified_num = str(num)
    return int(stringified_num[::-1])

def isPalindrome(num):
    '''Takes a positive int num, returns true if num is a palindrome'''
    return reverse(num) == num

# Test
num = eval(input("Enter integer: "))
print(isPalindrome(num))
