3,227 PointsI don't get it
Not sure exactly how to write this. I know how to make a class method, but after that I'm lost.
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)
@from_string
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)

230,688 PointsActually, the decorator for a class method is "@classmethod
", no matter what the name is. The name will appear right below in the "def" line, like any other method. From there it's much the same except that the first argument (typically "cls
") will represent the class itself instead of "self".
Give it an another shot now and write again if you still have trouble.
