Not sure what I did wrong here

The only error message I get is "Bummer: Try again!"

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

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

    def __iter__(self):
        yield from self.pattern

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