Additional unpacking generalizations

One of the recent new features, introduced in Python 3.5, is the ability to extend the iterable (*) and dictionary (**) unpacking operators to allow unpacking in more positions, an arbitrary number of times, and in additional circumstances. I'll present you with an example concerning function calls:

# additional.unpacking.pydef additional(*args, **kwargs):    print(args)    print(kwargs)args1 = (1, 2, 3)args2 = [4, 5]kwargs1 = dict(option1=10, option2=20)kwargs2 = {'option3': 30}additional(*args1, *args2, **kwargs1, **kwargs2)

In the previous example, we defined a simple function that prints its input arguments, args and kwargs. The new feature lies in the way we call this function. Notice how we can unpack ...
