2,334 PointsDidn't get the right pattern
I keep on getting this error.
Thanks, Sabine
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, output):
stringList = output.split('_')
pattern = []
for item in stringList:
if item == 'dash':
pattern.append('_')
elif item == 'dot':
pattern.append('.')
else:
pass
return cls(pattern)
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)

231,275 PointsYou're nearly there! I see you changed the pattern representation for "dash" to be underscore, but you apparently also changed the separator character that you split the incoming string on.
Those strings will still have hyphens separating the element names.
