hi, OOP Morse code doesnt work. here is my code, but it doesnt seem to be working.

class Letter(): def init(self, pattern=None): self.pattern = pattern def str(self, pattern): result = [] for i in pattern: if i == '.': list = "dot" elif i =='_': list = "dash" result.append(list) result = "-".join(result)
return result

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

morse.py
class Letter():
    def __init__(self, pattern=None):
        self.pattern = pattern
    def __str__(self, pattern):
      result = []
      for i in pattern:
        if i == '.':
          list = "dot"
        elif i =='_':
          list = "dash"
        result.append(list)
      result = "-".join(result)  
      return result


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

You're really close there! But the "__str__" function shouldn't take a separate pattern argument. Instead, it should work on the internally stored pattern in the object ("self.pattern"). Other than that, your process looks good!
