python五子棋小游戏的源码

以下是一个简单的 Python 五子棋小游戏的源码：

import numpy as np

BOARD_SIZE = 15  # 棋盘大小
EMPTY = 0  # 空棋子
BLACK = 1  # 黑棋子
WHITE = 2  # 白棋子


class Board:
    def __init__(self):

            self.current_player = WHITE if self.current_player == BLACK else BLACK
            return True
        else:
            return False

                    # 右上到左下
                    if i >= 4 and j <= BOARD_SIZE - 5:
                        if self.board[i][j] == self.board[i-1][j+1] == self.board[i-2][j+2] == self.board[i-3][j+3] == self.board[i-4][j+4]:

                        break

            print()


if __name__ == '__main__':
    game = Game()
    game.start()

使用方法：

- 下载源码并保存到本地；
- 在终端或命令行窗口中进入源码所在目录；
- 输入 `python gomoku.py` 命令运行程序；
- 根据提示输入坐标下棋。

注意：此程序为简单版本，可能存在一些小问题，欢迎大家提出改进意见。
