Im I wrong or the website??

The code looks right however its giving me an error of "Couldn't import Letter". Which to me feels like the code Challenge has messed up. Is there any way to fix? Or am I wrong?

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 == '.':
        return '-'.join(output)

    def from_string(cls, string):
        split_str = string.split("-")
        output = []
        for text in split_str:
            if text == "dash":

        return cls(output)

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

You have some typos:

1) @classmothod instead of @classmethod

2) Inside from_string you have (twice) output.appedn instead of output.append
