How do I produce the correct result for this code challenge with the iter method?
class Letter:
def __init__(self, pattern=None):
self.pattern = pattern
def __iter__(self.pattern):
yield from 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)

Also on the yield from you need self.pattern
