python围棋棋盘单机鼠标左键出黑棋鼠标右击下右棋子

下面是一个简单的围棋棋盘的实现，可以用鼠标左键下黑棋，右键下白棋：

import pygame

# 初始化Pygame
pygame.init()

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# 定义棋盘大小和每个格子的大小
BOARD_SIZE = 500
GRID_SIZE = BOARD_SIZE // 19

# 创建窗口
screen = pygame.display.set_mode((BOARD_SIZE, BOARD_SIZE))
pygame.display.set_caption("围棋棋盘")

# 创建棋盘
board = [[0] * 19 for _ in range(19)]

# 游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            # 获取鼠标位置
            pos = pygame.mouse.get_pos()
            x = pos[0] // GRID_SIZE
            y = pos[1] // GRID_SIZE
            # 左键下黑棋
            if event.button == 1:
                board[y][x] = 1
            # 右键下白棋
            elif event.button == 3:
                board[y][x] = 2

    # 绘制棋盘和棋子
    screen.fill(WHITE)
    for i in range(19):
        pygame.draw.line(screen, BLACK, (GRID_SIZE, (i+1)*GRID_SIZE), (BOARD_SIZE-GRID_SIZE, (i+1)*GRID_SIZE))
        pygame.draw.line(screen, BLACK, ((i+1)*GRID_SIZE, GRID_SIZE), ((i+1)*GRID_SIZE, BOARD_SIZE-GRID_SIZE))
    for i in range(19):
        for j in range(19):
            if board[i][j] == 1:
                pygame.draw.circle(screen, BLACK, ((j+1)*GRID_SIZE, (i+1)*GRID_SIZE), GRID_SIZE//2)
            elif board[i][j] == 2:
                pygame.draw.circle(screen, WHITE, ((j+1)*GRID_SIZE, (i+1)*GRID_SIZE), GRID_SIZE//2)

    # 更新屏幕
    pygame.display.flip()

# 退出Pygame
pygame.quit()

需要注意的是，这只是一个简单的实现，还有很多可以完善的地方，比如判断是否有落子禁手、判断胜负等。
