morse.py works in workspaces but not in code challenge

The below code returns the correct code challenge pattern when I run it in workspaces, but the code challenge is still telling me it's not getting the right pattern. Why?

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_convert):
        new_str = []
        for char in str_convert:
            if char == 'dash':
                new_str.append('_')
            if char == 'dot':
                new_str.append('.')
        return cls(new_str)


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

test = Letter.from_string(['dot', 'dash', 'dot', 'dot'])
print(test.pattern)
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_convert):
        new_str = []
        for char in str_convert:
            if char == 'dash':
                new_str.append('_')
            if char == 'dot':
                new_str.append('.')
        return cls(new_str)




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

Thank You Andrey,

I understand my mistake.
