sum_two sample solution parameter about interactive-coding-challenges

[suhasthegame]

Hey Mark,
We can still solve this by using the variable argument syntax in the sum_two method

class Solution(object):
def sum_two(self, *val):
return sum(val)

Run the test cases and it will pass all of them. Appreciate any feedback from your side.

For the sum_two_challenge notebook (link), the Solution class template only takes one parameter:

class Solution(object):

    def sum_two(self, val):
        # TODO: Implement me
        pass

That should change to two parameters:

class Solution(object):

    def sum_two(self, a, b):
        # TODO: Implement me
        pass

Otherwise a TypeError is raised with the message:

TypeError: sum_two() takes 2 positional arguments but 3 were given

def sum_two(self, *val):
return val

you can enter multiple values when we use (*args)
and (**kwargs) takes keywords arguments
