请你用python编写一个围棋程序

下面是一个简单的围棋程序示例，使用 Python 语言编写。它使用 Pygame 库来构建 GUI 界面，支持两个人在同一计算机上进行游戏。

import pygame
import sys

# 初始化 Pygame
pygame.init()

# 定义棋盘大小和单元格大小
BOARD_SIZE = (480, 480)
CELL_SIZE = 60

# 定义棋子颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# 创建棋盘表格
board = [[0] * 8 for i in range(8)]

# 定义当前玩家和下一位玩家
current_player = 1
next_player = 2

# 定义 Pygame 窗口
screen = pygame.display.set_mode(BOARD_SIZE)

# 画棋盘
def draw_board():
    for row in range(8):
        for col in range(8):
            x = col * CELL_SIZE
            y = row * CELL_SIZE
            pygame.draw.rect(screen, BLACK, (x, y, CELL_SIZE, CELL_SIZE), 2)

# 画棋子
def draw_piece(row, col, player):
    x = col * CELL_SIZE + CELL_SIZE // 2
    y = row * CELL_SIZE + CELL_SIZE // 2
    if player == 1:
        pygame.draw.circle(screen, BLACK, (x, y), CELL_SIZE // 2 - 4)
    else:
        pygame.draw.circle(screen, WHITE, (x, y), CELL_SIZE // 2 - 4)

# 检查是否有气
def check_liberty(row, col):
    if row > 0 and board[row - 1][col] == 0:
        return True
    if row < 7 and board[row + 1][col] == 0:
        return True
    if col > 0 and board[row][col - 1] == 0:
        return True
    if col < 7 and board[row][col + 1] == 0:
        return True
    return False

# 检查是否可以吃子
def check_capture(row, col, player):
    if row > 0 and board[row - 1][col] == 3 - player and not check_liberty(row - 1, col):
        return True
    if row < 7 and board[row + 1][col] == 3 - player and not check_liberty(row + 1, col):
        return True
    if col > 0 and board[row][col - 1] == 3 - player and not check_liberty(row, col - 1):
        return True
    if col < 7 and board[row][col + 1] == 3 - player and not check_liberty(row, col + 1):
        return True
    return False

# 主游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        elif event.type == pygame.MOUSEBUTTONDOWN:
            # 获取鼠标点击的位置
            pos = pygame.mouse.get_pos()
            row = pos[1] // CELL_SIZE
            col = pos[0] // CELL_SIZE

            # 检查该位置是否为空
            if board[row][col] == 0:
                # 检查是否落子后无气或可吃子
                board[row][col] = current_player
                if not check_liberty(row, col) and not check_capture(row, col, current_player):
                    board[row][col] = 0
                    continue

                # 检查是否吃子
                if check_capture(row, col, current_player):
                    if row > 0 and board[row - 1][col] == 3 - current_player and not check_liberty(row - 1, col):
                        board[row - 1][col] = 0
                    if row < 7 and board[row + 1][col] == 3 - current_player and not check_liberty(row + 1, col):
                        board[row + 1][col] = 0
                    if col > 0 and board[row][col - 1] == 3 - current_player and not check_liberty(row, col - 1):
                        board[row][col - 1] = 0
                    if col < 7 and board[row][col + 1] == 3 - current_player and not check_liberty(row, col + 1):
                        board[row][col + 1] = 0

                # 下棋
                draw_piece(row, col, current_player)

                # 更新玩家
                temp = current_player
                current_player = next_player
                next_player = temp

    # 绘制界面
    draw_board()
    for row in range(8):
        for col in range(8):
            if board[row][col] != 0:
                draw_piece(row, col, board[row][col])
    pygame.display.update()

这个程序使用 Pygame 库创建了一个窗口和一个棋盘。它使用一个二维数组 `board` 来表示棋盘状态，其中 0 表示空白，1 表示黑子，2 表示白子。程序还定义了几个函数来绘制棋盘和棋子，以及检查是否有气和可吃子。在主游戏循环中，程序等待玩家点击棋盘上的位置，并在点击时下棋，更新棋盘状态，并检查是否有气和可吃子。程序还支持两个人交替下棋。
