I am looking for a Python chess engine package. It must be fully contained in Python, I don't want to download separate files for the engine itself and link them up somehow.
All I want it to be able to do is take a FEN and provide best move. It should obviously be a strong engine, at least 2500 rating.
I have experience with only SunFish, but I doubt it's 2500+ level.
This link should help you. If you're not happy with the folks at talkchess, you probably won't find a better answer anywhere else.
An alternative to Sunfish is PyChess: http://pychess.org/ (or https://github.com/pychess/pychess)
It's stronger than sunfish (has 2100 bullet rating on lichess: https://lichess.org/@/PyChessBot ) and also allows playing chess variants, such as antichess or fisher random.
It has a lot more code than sunfish though, so pulling it out as a separate library takes a bit more work. See also http://talkchess.com/forum3/viewtopic.php?t=67025
