Python Python Testing Be Assertive assertIn

As I get to the end of this series of Python courses, I am increasingly finding myself in over my head. I did not understand parts of the previous video, but I think I got enough to take a stab at this. Not enough for it to pass though.

import unittest

from string_fun import get_anagrams

class AnagramTests(unittest.TestCase):
    def test_in_anagrams(self):
import itertools

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]

def get_anagrams(*yarn):
    """Return a list of anagrams for a string."""
    # If only one letter came in, return it
    if yarn:
        if len(yarn[0]) <= 1:
            return list(yarn)
        raise ValueError("Must provide at least two letters")

    # Get all of the words from the dictionary
    words = set([
        w.strip().lower() for w in open('words.txt')

    output = set()
    for thread in yarn:
        thread = thread.lower()
        # Find all possible anagrams
        for i in range(2, len(thread)):
            fibers = set(
                [''.join(w) for w in itertools.permutations(thread, i)]

    # Finally, return all of the combinations that are in the dictionary
    return sorted(list(output))

You have it except for two parts. You need to actually call get_anagrams (and it doesn't belong to self, it's just a standalone function), and your arguments are backwards for assertIn. You're asserting that the first argument is in the second argument.
