assertTrue task 1

I cannot do task 1 of assertTrue and False I think I did it right but not sure why it is saying an error.

tests.py 
import unittest

from string_fun import is_palindrome


class PalindromeTestCase(unittest.TestCase):
    def test_good_palindrome(self):
        pass      
    def test_bad_palindrome(self):
        pass
    def test_is_palindrome(self):
        self.assertTrue("tacocat")
string_fun.py 
def is_palindrome(yarn):
    """Return whether or not a string is a palindrome.

    A palindrome is a word/phrase that's the same in
    both directions.
    """
    return yarn == yarn[::-1]

Hello Ahmed.

Let's see if we can sort this out:

The first thing I notice is that you have created an extra function that is not needed. You simply need to use one of the two provided by default.

So, guess which one? :) Yes, the test_good_palindrome one!

Delete that "pass" keyword inside the function and proceed with the code:

If you have a look at the other file, string_fun.py, you will notice that it declares a function that comes very handy here. Your line of code is pretty close to the right one, you just need to use the is_palindrome function (from string_fun.py) passing in the word "tacocat" or any other palindrome that comes to your mind...

That should do the job!

Let me know if this helps or if you are still stuck.
