QUESTION
I've been using type hinting as of late. In some cases, it would be useful to force the type automatically instead of the boilerplate of isinstance
for every type hinted variable. It would be seamless to have a decorator that could do this but I'm not even sure if this is possible in Python.
How would one implement a decorator that forces the type hinting? For example, having the capabilities of function g
but the syntax of function h
.

You can use assert_types like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
