Hi HN! I'm pleased to present PyKidos [1], a quick-and-dirty web application I built in a few days to teach my 8-year-old kid basic programming concepts using Python. I tried several existing apps but couldn't find one that met all my criteria: - Fully browser-based, no need to install anything - Supports Python - Open-source and customizable - Simple UI/UX - Includes simple graphical elements like a grid (my kid thought my plain IPython terminal was too "boring") So I just built my own. PyKidos provides a playground where you can introduce various programming and math concepts to your child, such as: - Variables - Basic mathematical operations - Loops - Conditional statements - Modular arithmetic - Vectors - Functions - Coordinate systems - Color systems - Trigonometric functions - Matrices - And more. Features: - Completely client-side: data is stored only in your browser (localStorage). - Utilizes Pyodide [2], a CPython port to WebAssembly, with support for NumPy and other scientific libraries. - Includes a Unicode emoji picker and color picker. - Allows manipulation of a grid (cell colors and text, including Unicode emojis) using Python. - Reacts to click and keyboard events within the grid. - Supports animations. - Enables local download of your Python scripts. - Facilitates code sharing through a URL containing the entire code and data. PyKidos is still quite rough around the edges since I primarily built it for my own needs, but I hope it proves helpful to others. In particular, I didn't take the time to ensure it runs smoothly on mobile devices, different browsers, or operating systems. Feel free to report issues, ask questions, offer suggestions, or submit pull requests.
