Question

Don't understand what i have to do further for this code to run properly. Please help if you can. Thanks.

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, strings):
        morse = strings.split('-')
        pattern = []
        for strings in pattern:
            if strings == 'dot':
                pattern.append('.')
            elif strings == 'dash':
                pattern.append('-')
        return cls(pattern)

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

You're very close! But there's two issues yet (and a suggestion):

after splitting the "strings" into "morse", you should use it as the loop iterator instead of "pattern"
the character that represents a dash in the pattern should be underscore ('_') instead of hyphen ('-')
while not a technical issue, you might want to choose a unique name for the loop variable
