As a user you do not need to worry about conversions. ChessBase can read and write PGN games files. On the other hand, the use of storage space is much less efficient than in the ChessBase format – you need about seven times as much space to store the same games in PGN. It is especially popular on the Internet because the games are stored as plain textfiles and can be edited – or theoretically even typed in completely – with a simple text editor. It takes a over an hour for my computer to process.The PGN or Portable Game Notation format is an internationally recognized standard for recording games in ASCII notation. The PGN file is 92.8 MB and includes 121,333 games and 8,155,187 individual moves. This first example uses the January 2013 Standard Rated games database from Lichess. This can be useful for processing large files without having to load the entire file into memory at once. The pgn module provides a read_game function that can be used to iterate over the games in the PGN file one at a time. You can use the pgn module of the python-chess library to read a large file with many PGNs in it. Open a PGN File with Multiple Games and Parse the Headers Using these three resources in combination seems to be a promising way to explore chess in an analytically rigorous manner. Python-chess is a Python library for working with chess in Python, providing functionality to create and modify chess games, analyze chess positions, generate and parse chess notation, and interact with chess engines.
Pandas also offers powerful tools for data cleaning, aggregation, filtering, and visualization, making it a popular choice for data scientists and analysts. It provides easy-to-use data structures and data analysis tools for handling and manipulating structured data, including time series, tabular, and matrix data. Pandas is a popular open-source data manipulation and analysis library for Python. It is a valuable resource for chess players of all levels who want to improve their game and learn from the strategies and tactics of other players. The database is regularly updated and contains millions of games, which can be downloaded in a variety of formats for analysis and study purposes. The Lichess games database (linked here) is a collection of chess games played on the Lichess website, which is a popular online chess platform.
