In this tutorial, we will see how to create and maintain a Python package, especially relying on Cookiecutter, by Audrey Roy Greenfeld, and PyCharm. Even for those who do not plan to create packages in a near future, this tutorial is useful to learn how to structure a Python project, document it with Sphinx, test it with doctest, etc.
