Not sure what is wrong.
The question is saying that it is not outputting the right pattern. Though when I run it in Visual Studio I am getting the correct instance with the right pattern.
Any help would be much appreciated.
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, text): pattern =  for pat in text.split("-"): if pat == "dot": pattern.append(".") elif pat == "dash": pattern.append("-") return cls(pattern) class S(Letter): def __init__(self): pattern = ['.', '.', '.'] super().__init__(pattern)
This happens a lot with this challenge. For 'dash' you are appending a hyphen instead of an underscore.
