# it's a decorator,so a separate class+method don't need to be defined
# for each function and the class does not need to be instantiated,# as with Alex Hall's answer
def fact(self,n):
if n > 0:
return n * self(n-1) # doesn't need to be self(self,n-1),# as with lkraider's answer
else:
return 1
print(fact(10)) # works,as opposed to dursk's answer
