Python classmethod - why does this not pass? I get the correct pattern in my workspace.
Can someone help me find the error in this code? It keeps saying "Bummer: Didn't get the right pattern"
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, item): x =  x = item.split("-") length = len(x) count = 0 if count < length: if x[count] == "dash": x[count] = "_" count = count + 1 if x[count] == "dot": x[count] = "." count = count + 1 return cls(x) class S(Letter): def __init__(self): pattern = ['.', '.', '.'] super().__init__(pattern)

You have used:
if count < length:
That will only be evaluated once. Based on the rest of your code shouldn't you be using

Did you try it with the example string in the instructions ("dash-dot")? You might need a loop to process arguments that have more than one element.
