Python Python Collections (2016, retired 2019) Tuples Packing

Couldn't multiply correctly

I don't see why multiplying the interating variable (nums) by it self won't return the product?

def multiply(*args): 
    for num in args: 
    return total

Remember that the task is to return the total product "of all of the supplied arguments". But "num * num" is the square of just one of the arguments. And if you reassign total with this in a loop, then when the loop finishes total will contain the square of the last argument.

Try again, and remember that you want to multiply the arguments by each other, and retain (instead of replace) the product during the loop.

Ah! The light bulb just went off. Thank you!
