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):
self.assertIn(self.get_anagram,'house')
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))

Treehouse Guest TeacherYou 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.
