用python设计一个五子棋代码，要求运行界面可视化，提供必要的注释和丰富的功能，胜负判断

好的，以下是五子棋的Python代码，注释和可视化界面。代码中包含胜负判断和丰富的功能。

# 导入必要的库
import pygame
import sys
import numpy as np

# 初始化Pygame
pygame.init()

# 定义常量
WIDTH = 640      # 界面宽度
HEIGHT = 640     # 界面高度
LINE_WIDTH = 4   # 棋盘线宽
ROWS = 15        # 棋盘行数
COLS = 15        # 棋盘列数
BLACK = (0, 0, 0)   # 黑色
WHITE = (255, 255, 255)  # 白色

# 初始化界面
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption('五子棋')

# 画棋盘
def draw_board():
    for i in range(ROWS):
        pygame.draw.line(screen, BLACK, (LINE_WIDTH, LINE_WIDTH + i * (HEIGHT - LINE_WIDTH * 2) / (ROWS - 1)), (WIDTH - LINE_WIDTH, LINE_WIDTH + i * (HEIGHT - LINE_WIDTH * 2) / (ROWS - 1)), LINE_WIDTH)
    for i in range(COLS):
        pygame.draw.line(screen, BLACK, (LINE_WIDTH + i * (WIDTH - LINE_WIDTH * 2) / (COLS - 1), LINE_WIDTH), (LINE_WIDTH + i * (WIDTH - LINE_WIDTH * 2) / (COLS - 1), HEIGHT - LINE_WIDTH), LINE_WIDTH)

# 初始化棋盘
board = np.zeros((ROWS, COLS))

# 落子
def draw_piece(row, col, player):
    pygame.draw.circle(screen, player, (int(LINE_WIDTH + col * (WIDTH - LINE_WIDTH * 2) / (COLS - 1)), int(LINE_WIDTH + row * (HEIGHT - LINE_WIDTH * 2) / (ROWS - 1))), int((WIDTH - LINE_WIDTH * 2) / (COLS * 2)))

# 判断胜负
def win(player):
    # 判断行
    for i in range(ROWS):
        count = 0
        for j in range(COLS):
            if board[i][j] == player:
                count += 1
                if count == 5:
                    return True
            else:
                count = 0
    # 判断列
    for j in range(COLS):
        count = 0
        for i in range(ROWS):
            if board[i][j] == player:
                count += 1
                if count == 5:
                    return True
            else:
                count = 0
    # 判断对角线
    for i in range(ROWS - 4):
        for j in range(COLS - 4):
            if board[i][j] == player and board[i+1][j+1] == player and board[i+2][j+2] == player and board[i+3][j+3] == player and board[i+4][j+4] == player:
                return True
    # 判断反对角线
    for i in range(ROWS - 4):
        for j in range(4, COLS):
            if board[i][j] == player and board[i+1][j-1] == player and board[i+2][j-2] == player and board[i+3][j-3] == player and board[i+4][j-4] == player:
                return True
    return False

# 初始化玩家和计数器
player = BLACK
counter = 0

# 游戏循环
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            # 获取鼠标位置
            mouse_x, mouse_y = pygame.mouse.get_pos()
            # 计算行列
            row = int((mouse_y - LINE_WIDTH) / ((HEIGHT - LINE_WIDTH * 2) / (ROWS - 1)))
            col = int((mouse_x - LINE_WIDTH) / ((WIDTH - LINE_WIDTH * 2) / (COLS - 1)))
            # 落子
            if board[row][col] == 0:
                draw_piece(row, col, player)
                board[row][col] = player
                # 判断胜负
                if win(player):
                    print("Player " + str(player) + " wins!")
                    pygame.time.wait(5000)
                    sys.exit()
                # 切换玩家
                player = WHITE if player == BLACK else BLACK
                counter += 1
                # 判断是否平局
                if counter == ROWS * COLS:
                    print("It's a draw!")
                    pygame.time.wait(5000)
                    sys.exit()

    # 绘制棋盘
    screen.fill(WHITE)
    draw_board()

    # 绘制棋子
    for i in range(ROWS):
        for j in range(COLS):
            if board[i][j] != 0:
                draw_piece(i, j, BLACK if board[i][j] == 1 else WHITE)

    pygame.display.update()

这是一个基础版的五子棋代码，你可以根据自己的需求进行修改和扩展。运行代码后，你可以在界面上落子并看到棋盘和棋子的变化，当有玩家获胜或者平局时，会在控制台输出对应信息并等待5秒后退出游戏。
