typer: Feel free to learn more on the about typer by checking the documentation. It's a great project and if you're interested in supporting it we highly recommend talking to your employer to see if you can sponsor the maintainer.
In this series of videos we've shown you how to use typer to create command line apps. What we really hope though is that they've also inspired you to actually go out there and write some. Command line tools are amazing steppings stones for automation. They can be scheduled easily but you can also easily run them on other machines. So feel free to take a moment and wonder what part of your day-to-day you might be able to automate.
