Question:The get_anagrams() function takes one or more words and returns anagrams for each of them as a list. Finish the test_in_anagrams() test to check that the anagrams for the string "treehouse" contains the word "house".
I'm pretty sure it's just that I'm not understanding this fully. I'm going to go back through the course after this post and see if I can get a better understanding of this testing course. I'm fairly new to python testing so anything helps :).
Thanks, -Devin
Code:
import unittest
from string_fun import get_anagrams
class AnagramTests(unittest.TestCase):
def test_in_anagrams(self):
get_anagrams(assertIn("house", "treehouse"))
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))

). Supply this call with "house"
for the item you're looking for, and the collection of all anagrams from get_anagrams.

class AnagramTests(unittest.TestCase):
def test_in_anagrams(self):
self.assertIn('house', get_anagrams('treehouse'))

66,191 PointsHere's my updated code, I'm still getting it wrong but I think you led me onto the right track.

66,191 PointsI figured it out, all I had to do is pass Treehouse as a string to get_anagrams, thanks for the help!
