 - Avoid using CPython's standard library for web operations, GUI (like tkinter), or I/O as it is very synchronous/platform-specific and will probably stay that way. In terms of GUI alternatives, [pygame_gui](https://pypi.org/project/pygame_gui) works on top of [pygame-ce](https://pyga.me), [Panda3D](https://www.panda3d.org/) provides [directgui](https://docs.panda3d.org/1.10/python/programming/gui/directgui/index) and Harfang3D provides imgui. They are all cross-platform.

 There is actually none, because Python-WASM is just a web-friendly version of CPython REPL with [some added facilities](https://discuss.python.org/t/status-of-wasm-in-cpythons-main-branch/15542/12?u=pmp-p). Most desktop code will run (and continue to run) with only a few changes.
