Please help with all the coding instructions with explanation for the logic Please !!!
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): pattern =  return cls(pattern) class S(Letter): def __init__(self): pattern = ['.', '.', '.'] super().__init__(pattern)

The flow will be of the form
# split pattern argument into individual words # loop over individual words creating a new list # if word is "dash" add a "_", if a "dot", add a "." # instantiate an new `cls` with the pattern argument the new word list # return this instance
Post back if you need more hints. Good Luck!!
