shogi.COLORS Range (0, 2). 0,1.

shogi.CSA.Parser.parse_file(filepath) It is converted from a CSA file to a dictionary with four keys: names, sfen, moves, and win. This dictionary is included in the list as an element. If you add [0] after (filepath), you can retrieve only the dictionary.

shogi.PIECE_TYPES_WITH_NONE Range (0, 16). 0,1, ..., 15.0 is blank, and 1 and later indicate the type of piece.

shogi.MAX_PIECES_IN_HAND [0, 18, 4, 4, 4, 4, 2, 2, 0, 0, 0, 0, 0, 0, 0]. The meaning of the number of pieces you have. Indexes 1-7 probably look like this: shogi.MAX_PIECES_IN_HAND [1] = 18: Ayumu shogi.MAX_PIECES_IN_HAND [2] = 4: Lance shogi.MAX_PIECES_IN_HAND [3] = 4: Keima shogi.MAX_PIECES_IN_HAND [4] = 4: Silver shogi.MAX_PIECES_IN_HAND [5] = 4: Fri shogi.MAX_PIECES_IN_HAND [6] = 2: Corner shogi.MAX_PIECES_IN_HAND [7] = 2: Rook

Move class

from_square A variable that represents the movement source when the board surface is represented by a numerical value from 0 to 80. The quotient when divided by 9 is the y coordinate, and the remainder is the x coordinate. The xy coordinate is 0 origin.

Board class

A class that represents an aspect. By the way, you can display the board in two dimensions with print (board).

piece_bb An array of 15 elements. Each element indicates the arrangement of each piece. 0: blank, 1: step, 2: incense, ... bit board. The bit board is as follows. Each element is a decimal number display of 81 digits (= 81 squares) in binary (that is, bit board). If you want to display 81 decimal digits, you can print ('{: 0 = 81b}'. format (decimal value)).

occupied An array of two elements. Each element is the position of the piece occupied by the first move and the second move. bit board.

pieces_in_hand An array of two elements. Each element is a dictionary type that shows which piece (= key) and how many pieces (= value) the first move and the second move have.
