...It hooks into Python’s import machinery so that when you reference a GitHub path, it fetches the code, stores it locally (often with caching), and makes it importable in the current environment. This is helpful for prototyping, teaching, or quickly exploring other people’s utilities without polluting your global site-packages. It also demonstrates how flexible Python’s import system is and can be used as a reference for custom importers. While not a substitute for proper packaging, it’s a clever shortcut for rapid experimentation.
