3,689 PointsHow would I make the list callable
A getting an error that says list is not callable. How would i rectify that
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):
new_list = []
my_list = string.split('-')
for item in my_list():
if item == ('dot'):
new_list.append('.')
elif item == ('dash'):
new_item.append('-')
return cls(pattern)
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)

231,248 PointsYou don't want to make the list callable, you just want to stop trying to "call" the list. That's one of a few issues:
- there should be no parentheses in "
for item in my_list:
" - the reference to "new_item" is undefined and should be "new_list" instead
- the reference to "pattern" is undefined and should also be to "new_list"
- a "dash" is being converted into a hyphen ('-') but should be an underscore ('_')
