Python Python Collections (2016, retired 2019) Tuples Packing

The error says 'Couldn't find multiply' I just get this error using *args as an argument in the function.

I would really love better errors when doing these assignments.

twoples.py 
def multiply(*args):
    list = []
    for num in args:
        list.append(int(num))
    return reduce(lambda x, y: x * y, list, 1)

I see four issues:

  • "from functools import reduce"
  • the arguments aren't necessarily integers, converting them could produce incorrect results
  • "list" is the name of a built-in, so not a good choice for a variable name
  • "list" is not needed since "args" can be passed directly to reduce

And you can omit the initializer since multiplying with 1 is an identity operation.
