PyMine-Net - an extensible and modular Minecraft networking library in Python
PyMine-net is no longer maintained, however, in it's place, a new project called mcproto was created, so if you're here looking for a library that provides an easy way to work with the minecraft's protocol, feel free to check it out instead!
- Buffer class with methods for dealing with various types and data formats used by Minecraft
- High level abstractions for packets with a system to seperate different protocol's packets
- Miscellaneous classes for dealing with different Minecraft data structures relevant to networking
