Im trying to pass this question but just couldn't understand what's telling me to do. i looked at the code that was in the video and still didn't get what I'm suppose to do, any suggestions are appreciated ?
import unittest
from string_fun import get_anagrams
class AnagramTestCase(unittest.TestCase):
def test_empty_string(self):
with self.assertRaises(ValueError):
get_anagrams()
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)
elif len(yarn[0] == 0):
raise ValueError("Must provide at least two letters")
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))

The challenge wants you to set up a unittest to make sure that when get_anagrams
gets an empty string passed in, it raises a ValueError. Your logic is correct, but don't forget that get_anagrams
takes an argument.
Good luck.
