Didn't get the right pattern

I keep on getting this error.

Thanks, Sabine

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, output):
        stringList = output.split('_')
        pattern = []
        for item in stringList:
            if item == 'dash':
                pattern.append('_')
            elif item == 'dot':
                pattern.append('.')
            else:
                pass
        return cls(pattern)


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

You're nearly there! I see you changed the pattern representation for "dash" to be underscore, but you apparently also changed the separator character that you split the incoming string on.

Those strings will still have hyphens separating the element names.
