Talk @Pygotham 2016
-------------------
I gave a talk at PyGotham 2016 on this library. Abstract can be found
`here <https://2016.pygotham.org/talks/324/abstractions-and-building/>`__.
Introduction
------------
Chess_py is an open source chess library written in Python designed to
aid in the creation of chess engines. Handles the chess so you can focus
on the engine.
Installation
------------
To use as a immediately start up a game between two human players in the
console, navigate inside the root directory of the package and run
main.py.
.. code:: bash
python main.py
To install package

Great! How do you use it? (*An Example*)
----------------------------------------
Chess_py has the capability of creating games between players, either
human, or AI
.. code:: python
import chess_py
from chess_py import Game, Human, color
""" Creates a Game with 2 humans.
When run, this will open the console,"""
new_game = Game(Human(color.white), Human(color.black))
""" After game is completed, outcome will be stored in result.
The integer result will be one of three values.
white wins - 0, black wins - 1, draw - 0.5 """
result = new_game.play()
To build a chess engine on with chess_py, inherit Player and implement
generate_move()
.. code:: python
import chess_py
from chess_py import Game, Human, color
# Engine which plays the move with the highest immediate material advantage
class MyEngine(chess_py.Player):
def __init__(self, input_color):
# Creates piece value scheme to specify value of each piece.
self.piece_values = chess_py.PieceValues.init_manual(PAWN_VALUE=1,
KNIGHT_VALUE=3,
BISHOP_VALUE=3,
ROOK_VALUE=5,
QUEEN_VALUE=9)
# Super call to
super(chess_py.Player, self).__init__(input_color)
def generate_move(self, position):
# position parameter is an object of type Board
# Finds all possible moves I can play.
moves = position.all_possible_moves(self.color)
# Initalizes best move and advantage after it has been played to dummy values.
best_move = None
best_move_advantage = -99
# Loops through possible moves
for move in moves:
""" advantage_as_result(move, piece_values) finds numerical advantage
as specified by piece value scheme above. Returns negative values for
positions of disadvantage. Returns +/-99 for checkmate. """
advantage = position.advantage_as_result(move, self.piece_values)
# If this move is better than best move, it is the best move.
if advantage >= best_move_advantage:
best_move = move
best_move_advantage = advantage
return best_move
# If file is run as script, a Game is set up between My_engine and Human and result is printed.
if __name__ == "__main__":
new_game = Game(MyEngine(color.white), Human(color.black))
# white wins - 0, black wins - 1, draw - 0.5
print("Result: ", new_game.play())
