How to make Python function which accepts tuple input?

Question

In Python 2, this function definition is valid:

def sv( (L, R) ):
    return L ^ R

However, in Python 3, a syntax error is returned on the second left parenthesis. I can't figure out why?

How do I instruct Python to accept a tuple as input?

Answer 1

Tuple parameter unpacking was removed in python 3.
