Python

I do not understand!

I have been rewatching the video but I just can't get past this code challenge. I would like it if someone could help me because I would really like to understand it. Thank you!

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

    def __str__(self):
        output = []
        for blip in self.pattern:
            if blip == '.':
                output.append('dot')
            else:
                output.append('dash')
        return '-'.join(output)

    def __iter__(self):
        yield from self.pattern



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

Never Mind I think my Computer glitched. I tried it again and it worked, don't know why.
