how to get the correct pattern here ?
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, string):
output = []
for i in string:
if i == 'dot':
output.append('.')
else :
output.append('_')
return cls(output)
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)
