Code working locally but unable to pass code challenge

I've tested the code I wrote on my local PC and it works fine but I am unable to pass the Treehouse Code Challenge.

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

    @classmethod
    def from_string(cls, abc):
        result = []
        for item in abc.split('-'):
            if item == 'dash':
                result.append('-')
            elif item == 'dot':
                result.append('.')
        return cls(result)


    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)


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