In this video, the third of a three-part series about object-oriented programming in Python, I show how to extend an existing class through inheritance (or subclassing). This allows you to create new classes that inherit all functionality of existing classes while extending or changing this functionality. (For more Python tutorials, see https://python.cogsci.nl. For the Rapunzel IDE, see https://rapunzel.cogsci.nl/)

Episode 6 of #PythonLiveLessons, a weekly live stream about Python code and more, hosted by Sebastiaan Mathôt. In this episode, well learn how to use pyproject.toml to add information about our package, and how to use flit to build our package and upload it to pypi so that users can easily install it with `pip install markdown_code_exec`.")
