I created the classmethod but what other things am i to pass in

In this case should i return the pattern or output list

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

    def __iter__(self):
        yield from self.pattern

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

     @classmethod
     def from_string(cls, pattern):
        return cls(output)




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

You won't need to pass anything into this method other than a string.

The instructions say the method "takes a string like "dash-dot" and creates an instance with the correct pattern". So you still need to:

  • convert the string argument into a pattern
  • return a new class instance that contains the pattern
