What am I looking at?

The Python MWE.

Structure

clients

Well, clients.

server

Code for the server

common

Shared stuff, like types and base classes

Setting up

Python

• 3.8 or newer

Optional but you should have this because the CI will definitely do this

• Install mypy
• Install mypy langserver on your editor (hopefully VSCode)

Running the code

• make init
• make run

Thoughts on Python

• mypy makes stuff type-safe. Try installing it and breaking some types. If you set up your editor properly to use the language server, it should redline upon save. Otherwise, run mypy . (This will be the command run by the C.I.)
• Python modules are known to be wonky (hence the sys.path.append stuff at some files requiring imports in parent directories). The workaround is ugly, but fine.
• Honestly, Python is easy to set up and easy to learn (if you don't know it)
• There are problems with coding it with 40+ people, but if the BaseClient has strongly enforced types, you shouldn't be able to merge stuff with failing types :-)
