pip install roblox-pyc

Python, Lunar, C, C++ Compiler for Roblox.

Python 3.13 (dev), C (all versions), C++ (all versions), Lunar -> Lua(u)

> This has NO RELATION with .pyc files, roblox-py, or roblox-ts

> C/C++ is still in progress.

> Python is fully implemented, all code should work because it supports the dev build of Python 3.13.

Features
