Conversely, we shouldn't see the word "code" in the list of anagrams for "treehouse". Add a new test named test_not_in_anagrams and use self.assertNotIn() to make sure "code" isn't in the anagrams for "treehouse".
import unittest
from string_fun import get_anagrams
class AnagramTests(unittest.TestCase):
def test_in_anagrams(self):
self.assertIn("house",get_anagrams("Treehouse"))
class AnagramTests(unittest.TestCase):
def test_not_in_anagrams(self):
with self.assertNotIn('code', get_anagrams('Treehouse'))
pass
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)
else:
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)]
)
output.update(fibers.intersection(words))
# Finally, return all of the combinations that are in the dictionary
return sorted(list(output))

Why are you defining another class called AnagramTests within AnagramTests, also the the string you pass to the get_anagrams function should be lowercase treehouse.
import unittest
from string_fun import get_anagrams
class AnagramTests(unittest.TestCase):
def test_in_anagrams(self):
self.assertIn("house",get_anagrams("treehouse"))
def test_not_in_anagrams(self):
self.assertNotIn('code', get_anagrams('treehouse'))
hope this helps
