Quick tip: reload Python modules in Jupyter with the autoreload magic method

If you are writing your own Python modules and you include them in your Jupyter notebooks you might notice that by default your code updates in the custom Python module are not reflected once the module has been load by Jupyter. You can fix this by adding %autoreload at the top of your notebook.

%load_ext autoreload
%autoreload 2
