not sure what I'm missing but this works in my IDE >>> from noclass import S >>> S().from_string("dash-dot")

Question

not sure why but this works in my IDE but not on the site

>>> from noclass import S
>>> S().from_string("dash-dot")
['_', '.']

I must be missing something

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, str):
        output = []
        for blip in str.split("-"):
            if blip == "dot":
                output.append('.')
            if blip == "dash":
                output.append('_')

        return output


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

You are very close! The challenge asks that you return an instance of the class with the pattern extracted from the string. This can be done in your return statement:

return cls(output)

Also, it is not a good practice to used reserved words or built-in functions names as variable names. Best to use “string” instead of str.

Post back if you need more help. Good luck!!!
