Hi Rungano

A Palindrome is when the string in reverse is the same. So i pass the is_palindrome function to the assertTrue as an argument and it should return True if the string 'tacocat' is a Palindrome and the same for the assertFalse. This is how i did it.

import unittest

from string_fun import is_palindrome


class PalindromeTestCase(unittest.TestCase):
    def test_good_palindrome(self):
        self.assertTrue(is_palindrome("tacocat"))

    def test_bad_palindrome(self):
        self.assertFalse(is_palindrome("nottacocat"))
