def multiply(*args):
    result = args[0] # This gets the first arg
    # Then iterate over the remaining args using slice.
    for arg in args[1:]:
        result *= arg
    return result

Marco’s code works if you change the initial value, total, from 0 to 1. This is because 1*a = a whereas 0*a = 0. This also avoids slicing.
