The fifth episode of #PythonLiveLessons, a weekly live stream about Python code and more, hosted by Sebastiaan Mathôt. In this episode, well turn our `markdown_code_exec` Python module, which we created in previous episodes, into a command-line application! Well learn about the `argparse` module to parse command-like arguments, about entry points, and about the if name main convention.ing")

The fourth episode of #PythonLiveLessons, a weekly live stream about Python code and more, hosted by Sebastiaan Mathôt. In this episode, well get started with git to host the code for our `markdown_code_exec` on GitHub. Well learn about the most important git commands: commit, push, pull, remote, and add.")
