Treehouse Moderator 68,441 PointsThe call to get_anagrams()
In the test test_empty_string
, the call to get_anagrams()
is missing the actual empty string ""
Edit:
Also, the pass
statement is no longer needed and should be removed for clarity.
Edit2: Typo fix

65,469 PointsYeah, the iPhone keyboard is awful. I always use Treehouse on a desktop computer
Sometimes, I just hate the word completion thing on the iPhone keyboard. Other times, I love it.
