The code checker is broken and needs to be fixed or output better error messages

@classmethod def from_string(cls, string): pattern = [] for word in string.split('-'): if word == 'dot': pattern.append('.') else: pattern.append('_')

    return cls(pattern)
morse.py 
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern

    def __iter__(self):
        yield from self.pattern

    def __str__(self):
        output = []
        for blip in self:
            if blip == '.':
                output.append('dot')
            else:
                output.append('dash')
        return '-'.join(output)

    @classmethod
    def from_string(cls, string):
        pattern = []
        for word in string.split('-'):
            if word == 'dot':
                pattern.append('.')
            else:
                pattern.append('_')

        return cls(pattern)



class S(Letter):
    def __init__(self):
         pattern = ['.', '.', '.']
         super().__init__(pattern)

Hi Tweekes,

This code passed for me on a copy and paste.

This can happen sometimes with the code challenges (I had it happen 3 or 4 times total in completing the beginner and intermediate Python tracks, so not too often but often enough to be a little frustrating).

You can try hitting the restart button at the top of the challenge and pasting it in fresh, but if that doesn't work you might need to log out of Treehouse, close all your browser windows, then come back and log in and try it again. That always solved it for me (but not before thinking there was something wrong with my code for way too long!).

Cheers,

Eric
