How to write a python function that adds all arguments?

Question

I\'d like to write a python function which adds all its arguments, using + operator. Number of arguments are not specified:

def my_func(*args):
         


        

Answer 1

If you definitely won't be using sum, then something like:

def func(*args, default=None):
    from operator import add
    try:
        return reduce(add, args)
    except TypeError as e:
        return default

or functools.reduce in Py3
