用Python写人机对战五子棋

好的，以下是一个简单的人机对战五子棋的Python代码，使用了基本的算法和GUI库Tkinter：

from tkinter import *
import random

# 初始化棋盘
def init_board():
    global board, player, winner, end
    board = []
    for i in range(15):
        row = []
        for j in range(15):
            row.append(0)
        board.append(row)
    player = 1
    winner = 0
    end = False

# 判断游戏是否结束
def check_win():
    global board, player, winner, end
    for i in range(15):
        for j in range(11):
            if board[i][j] == player and board[i][j+1] == player and board[i][j+2] == player and board[i][j+3] == player and board[i][j+4] == player:
                winner = player
                end = True
                return
    for i in range(11):
        for j in range(15):
            if board[i][j] == player and board[i+1][j] == player and board[i+2][j] == player and board[i+3][j] == player and board[i+4][j] == player:
                winner = player
                end = True
                return
    for i in range(11):
        for j in range(11):
            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:
                winner = player
                end = True
                return
    for i in range(11):
        for j in range(4, 15):
            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:
                winner = player
                end = True
                return
    for i in range(15):
        for j in range(15):
            if board[i][j] == 0:
                return
    winner = 0
    end = True

# 画棋盘
def draw_board():
    global board_canvas
    for i in range(15):
        board_canvas.create_line(30, 30+i*30, 450, 30+i*30)
        board_canvas.create_line(30+i*30, 30, 30+i*30, 450)

# 画棋子

    if player == 1:
        color = 'black'

    board_canvas.create_oval(x*30-15, y*30-15, x*30+15, y*30+15, fill=color, outline=color)

# 玩家落子
def player_move(event):
    global board, player, end
    if end:
        return

    draw_piece(x, y)
    check_win()
    if not end:
        player = 3 - player
        computer_move()

# 电脑落子
def computer_move():
    global board, player, end
    if end:
        return
    scores = []
    for i in range(15):
        row = []

                            else:

                row.append(score)

                max_positions.append((i, j))
    position = random.choice(max_positions)
    x = position[1] + 1

    board[y-1][x-1] = player
    draw_piece(x, y)
    check_win()
    if not end:

# 主程序
def main():
    global board_canvas
    root = Tk()
    root.title('五子棋')
    root.resizable(False, False)
    board_canvas = Canvas(root, width=480, height=480)
    board_canvas.pack()
    board_canvas.bind('<Button-1>', player_move)
    init_board()
    draw_board()
    root.mainloop()

if __name__ == '__main__':
    main()

运行代码后会弹出一个窗口，你可以通过鼠标点击棋盘上的空白位置进行落子。电脑会根据当前棋局情况计算分数，选择分数最高的位置落子。注意，这个算法非常简单，可能会有明显的漏洞，但足以体验五子棋人机对战的基本操作。
