Tuples multiply(*args)

I am really having a hard time with this one. Can someone point me in the right direction?

Thank you!

twoples.py 
def multiply(*args):
    product = 0

    for num in args:
        product = product * num

    return product

I found that it works if I change product to 1 instead of 0. However, I still don't understand what this is doing here. Can someone explain to me what this code is actually doing?

Thank you

Anything multiplied by 0 is 0.

So if you start with 0, no matter how many things you multiply with it, you'll still have 0.

On the other hand, if you start with 1, the first time you multiply you will get the value it was multiplied with. Then the product continues to increase with each other multiplier, exactly as the challenge expects.

Thank you. I don't know what is wrong with my brain today. It just went over my head a little.
