I can't figure out what's wrong in my code.

As far as I believe my code is correct but I don't know why I'm getting error. can anyone please give me any solution for this.

class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern
    def __str__(self):
        for n in self.pattern:
            if n=='.':
            elif n=='_':
        return "-".join(result)

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

You are SO close! You are reinitializing result to the empty list every loop. Move the initialization outside of the for loop and you'll be golden!

Post back if you have more questions. Good luck!!
