Python Calling A Raise Exception Instead Of Returning In Recursive Function

I have to check how much faster works a code where I throw exception to end a recursion instead of return My code with return looks this way: def factorial(self, n): if n==

Solution 1:

you need the try/except in the else part of this function ... since all calls will eventually raise this exception if you listen outside then all your work is lost

def factorial2(self, n):
    if n==0:
        raise Exc(1)
    else:
        try:
           return n* self.factorial2(n-1)
        except Exc:
           return n
