五子棋游戏相信大部分人都玩过，今天我们用python来实现一次

构建五子棋棋盘

from collections import namedtuple

Chessman = namedtuple('Chessman', 'Name Value Color')

BLACK_CHESSMAN = Chessman('黑子', 1, (45, 45, 45))

offset = [(1, 0), (0, 1), (1, 1), (1, -1)]


class Checkerboard:

    self._line_points = line_points
    self._checkerboard = [[0] * line_points for _ in range(line_points)]

    return self._checkerboard

  checkerboard = property(_get_checkerboard)

  # 判断是否可落子

    return self._checkerboard[point.Y][point.X] == 0

  def drop(self, chessman, point):
    """
    落子
    :param chessman:
    :param point:落子位置
    :return:若该子落下之后即可获胜，则返回获胜方，否则返回 None
