用python设计一款五子棋游戏，首先，五子棋游戏的规则是两个玩家轮流在棋盘上下黑白两种颜色的棋子，先在横、竖、斜线上形成连续的五个同色棋子者获胜。

好的，这里给您提供一份基于Python语言实现的五子棋游戏代码，希望能帮助您。

# 执行游戏
init_game()
play_game()

# 退出Pygame
pygame.quit()

该代码实现了基本的五子棋游戏规则，同时支持人机对弈，具有较好的可玩性。其中，棋盘的绘制、棋子的绘制、鼠标点击位置的获取、棋子是否在棋盘内、棋子是否重叠、是否有五个连续的同色棋子等功能均已实现。

需要注意的是，该代码仅为基础实现，还有很多细节和优化可以进行。比如，可以添加背景音乐、游戏结束后可以显示胜利者的信息等等。
