I started this due to the rage which can be caused by losing opportunities to write more elegant code, just because something „cannot be done” using JavaScript (or „JavaScript is not for that” etc.) This means that participating people must set an HTTP server to the port 50002, and optionally an OS-specific port: 50001 for Linux, 50010 for Mac, 51000 for Android, and if it is possible to make it usable on a such operating system like Windows, 60000, and on these ports, create a file named execute.py.cgi, which can evaluate arbitrary Python code in a sandbox (using venv), or at least in a limited environment, and accepts it through a POST argument named command. Thou can test whether your implementation works or not at test.html.
