python-chess is a pure Python chess library with move generation, move validation and support for common formats. It is open sourced at https://github.com/niklasf/python-chess
Based on a request for more detailed documentation this page gives some more details.

See Play Chess With a Webcam Issue 'Detecting Moves by a WebCAM' for how the terms below might be used.
AN Algebraic Notation
The Algebraic Notation describes moves on the chessboard by giving each field a name e.g. "a2" and thus allow to describe from which field e.g. "a2" to which other field e.g. "a4" a move has been performed.
Example a2 a4 move:
FEN Forsyth–Edwards Notation
The Forsyth–Edwards Notation describes a board position.
Examples:
Given a FEN you can continue playing from that position. E.g given 8/5k2/8/5K1P/8/8/8/8
a game might continue as:
PGN Portable Game Notation
The Portable Game Notation is used to record the course of a game for others to follow or replay.
Example:
[Event "Play Chess With a WebCam"] [Site "Willich, Germany"] [Date "2019-12-21 12:46:49"] [Round "1"] [White "Wolfgang"] [Black "Maria"] [Result "1-0"] 1. e4 e5 2. Bc4 Nc6 3. Qh5 Nf6 4. Qxf7# 1-0
If you paste the above PGN into https://lichess.org/paste you'll get the following result:
