A really cool but slightly arcane feature is the ability to “unpack” function arguments from sequences and dictionaries with the * and ** operators. These are sometimes also called "splat" operators.

They're most frequently used in Python function definitions along with the *args and **kwargs pattern.

Besides the * operator for unpacking sequences like tuples, lists, and generators into positional arguments there’s also the ** operator for unpacking keyword arguments from dictionaries.

In this video I'll give you an introduction to function argument unpacking in Python with a few straightforward examples.
