Live-reloading of Python Modules in the Python REPL / IPython / Jupyter Console
Often, I would work on a Python module and add changes to it live, which I would then want to test immediately. Piece of cake! Add the changes and execute the script again. Well, that’s certainly a way, but as modules get bigger, they tend to import other modules, or do some preliminary setup work.
With time, I have developed this practice of opening up a Python REPL (though I recommend IPython or the Jupyter Console for that), importing my in-progress module and singling out separate functions I would like to test.
