3,237 PointsAdd a new test named test_not_in_anagrams and use self.assertNotIn to make sure"code" isn't the anagrams for "treehouse"
Getting confused, need help from anyone please help:(
import unittest
from string_fun import get_anagrams
class AnagramTestCase(unittest.TestCase):
def test_nit_in_anagrams(self):
with self.assertNotIn(code):
get_anagrams('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))

to capture exceptions, assertIn and assertNotIn you'll deal with just like any other method call.
It looks like you removed the code for the first test, so you'll need to put that back in. You'll need both the test_in_anagrams and test_not_in_anagrams methods.

40,533 PointsThe test_empty_string and test_no_args are in a separate challenge from the test_in_anagrams and test_not_in_anagrams tests. You won't be required to port them over.
Your code for the test_empty_string method is actually what you'll want for the test_no_args method in the next part. To test against an empty string you'll want to call it like this:

3,237 PointsSorry Mr Dan, I am still confused. What exactly I am supposed to be doing. Can you please give hints or examples. I removed the the "test_not_in_anagrams" and put "test_empty_string" but it's still saying "bummer,try again"

40,533 PointsI'm kinda confused as to which challenge you're working on, so I'll just go over both:
assertIn Challenge:
assertRaises Challenge:
