PyLab is a mobile application designed to teach Python and let users write code on a smartphone. The project started as an ordinary code editor before expanding into an educational application with interactive lessons. Python is built into the app, so code can run on the phone itself. Users can work with libraries and launch their own projects without returning to a desktop computer. The article walks through what the author created with the tool and how the experience works in practice. The author then asks the technical community for its reaction, especially from people who consider programming on a phone a pointless pursuit.
