TreeHouse is a little buggy some times!

I'm sure the code is correct! but we dosen't work! I thing is a bug again, we do the same ug in past challenges tasks!

class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern

    def __str__(self):
        output = []
        for blip in self.pattern:
            if blip == '.':
        return '-'.join(output)

    def __iter__(self):
        yield from self.pattern

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

Hi there! The good news is that your code is correct! I just copy/pasted your code into the challenge and it passed with flying colors. Now the question becomes why it passes for me and not for you. My guess here is that it is something to do with caching either client-side or server side. You might try logging out of Treehouse, completely shutting down your browser, logging back in and then pasting in this code. If this still doesn't fix the issue you will likely need to contact help@teamtreehouse.com for assistance, because this should pass.

Hope this helps! :sparkles:
