Can someone please help me see why this doesn't work

I don't understand why it won't return the correct string. I've tried with an if, elif and else:continue but nothing seems to work

morse.py
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern

    def __str__(self):
        atts = []
        for elem in self:
            if elem == '.':
                atts.append("dot")
            else:
                atts.append("dash")
        return '-'.join(atts)



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

For your loop, you wrote:

        for elem in self:

But instead of "self" you need "self.pattern".
