I fail for some reason on one of the testing challenges but I'm not sure why:
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".
The response I get is:
Bummer! Didn't find a test for get_anagrams()
using self.assertIn()
import unittest
from string_fun import get_anagrams
class AnagramTests(unittest.TestCase):
def test_in_anagrams(self):
self.assertIn('house', 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))

14,136 PointsThanks that fixed the 2nd one - silly miss. I've double checked the first one but no typo that I can see. Am I using the assertIn() method incorrectly?

Thanks - Looked at it for far too long

Our get_anagrams() function raises a ValueError when you pass it an empty string. Finish the test to make sure this happens. You'll want to use assertRaises.
Answer:import unittest
from string_fun import get_anagrams
class AnagramTestCase(unittest.TestCase): def test_empty_string(self): with self.assertRaises(ValueError): get_anagrams("")

class AnagramTestCase(unittest.TestCase): def test_empty_string(self): with self.assertRaises(ValueError): get_anagrams('')
this worked for me

Now add a new test, test_no_args that should also assertRaises(ValueError). This time, call get_anagrams() with no arguments.
import unittest
from string_fun import get_anagrams
class AnagramTestCase(unittest.TestCase): def test_empty_string(self): with self.assertRaises(ValueError): get_anagrams("")
def test_no_args(self):
with self.assertRaises(ValueError):
get_anagrams()

14,136 PointsHmmm I'm most likely repeating the same mistake as I fail the next challenge too...
"Our get_anagrams() function raises a ValueError when you pass it an empty string. Finish the test to make sure this happens. You'll want to use assertRaises."
" Bummer! Didn't find a test for
get_anagrams()
usingself.assertRaises()
and an empty string"
