im pretty sure im doing this completely wrong at this point. Maybe im not reading the instructions right.
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, morse):
new_list = []
for i in morse:
if i == "dash":
new_list.append('_')
elif i == "dot":
new_list.append('.')
return new_list
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)

If you iterate over the argument directly, the loop will extract each character individually. So you probably want to split the string into a list of words first.
Then instead of returning the new pattern itself, the instructions ask you to return a new class instance with the correct pattern in it.
