Help with @classmethod - not sure where I'm going wrong

My code is attached - where am I going wrong?

The goal is to create a class method that will accept an input like "dash-dot-dot" and convert it into ['_', '.', '.']

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):
    stringList = string.split('-')
    output = []
    for blip in stringList:
        if (blip.lower() == 'dash'):
            output.append('_')
        elif (blip.lower() == 'dot'):
            output.append('.')
    return cls(output)


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