import-pypi. A devious Python 3 hack which abuses importlib.machinery to add a hook such that any time you type “import modulename” it checks to see if the module is installed and runs “pip install modulename” first if it isn’t. Intended as a joke, but if you habitually fire up temporary virtual environments for exploratory programming like I do this could actually be a neat little time-saver.
