Python Web Development Techdegree Student 3,402 PointsCouldn't multiply valid values together
Shouldn't this work?
We get every num in args and always multiply by the previous total
I'm also confused with other aspect of the challenge. If the variable type does not matter, what happens if the tupple has 2 strings together? We can't multiply them, right? How do we solve this?
Should we control for the error and write the code in a way that we can separate strings from ints?
Thanls in advance!

def multiply (base,*args):
total = base
for num in args:
total = total*num

In a real life scenario you probably would want some kind of input validation to ensure that only numbers are accepted as arguments, but for the purposes of this challenge it is fine to assume that only numbers will be passed. Passing a tuple that includes other data types could indeed cause an error.
