Python toString

I have the correct output but it says it is wrong. Please help!

morse.py 
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern
    def __str__(self):
        output = []
        for v in self.pattern:
            if v == ".":
                output.append("dot")
            if v == "-":
                output.append("dash")
        return "-".join(output)


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