What am i doing wrong it here?
class Letter:
def __init__(self, pattern=None):
self.pattern = pattern
def __iter__(self):
for item in self.pattern:
yield from self.pattern
def __str__(self):
output = []
for blip in self.pattern:
if blip == '.':
output.append('dot')
else:
output.append('dash')
return '-'.join(output)
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)

" in the body of the loop.
If you want to use "yield from
", it would replace the loop (and make the method even more compact).
