PyScript Updates: Bytecode Alliance, Pyodide, and MicroPython. Absolutely huge news about Python on the Web tucked into this announcement: Anaconda have managed to get a version of MicroPython compiled to WebAssembly running in the browser. Pyodide weighs in at around 6.5MB compressed, but the MicroPython build is just 303KB—the size of a large image. This makes Python in the web browser applicable to so many more potential areas.
