I am not sure why this function wont work

I don't know why , and it looks similar to the add function in the video

twoples.py 
def multiply(*args):
    nums=*args
    total = 0
    for num in nums:
        total = num * num
    return total

I think your problem is this line.

nums=*args

Maybe you want = ?

You could also rename args to nums, and remove this line. There is nothing special about the name args, only the * in front of it.

your total is going to be the last number in the list of *args squared. Also your total is set to 0 so if you fix the first problem, your total will always be 0.

Here's some hints:

  • you don't need "nums", you can iterate using "args"
  • the "total" needs to be the result of multiplying all numbers together, not just the square of one of them
  • you might need to start total with 1 instead of 0

how do you multiply the numbers together instead of squaring them

For each item in the loop, you might multiply it by the previous total and store it back into the total:

    total = 1          # start with 1 because "0 * anything" is still 0
    for num in args:
       total *= num    # this is the same as "total = total * num"
