五子棋人机对战实现简单代码

下面是一个简单的五子棋人机对战的代码示例：

import random

# 初始化棋盘
def init_board():
    board = [[' ' for _ in range(15)] for _ in range(15)]
    return board

# 打印棋盘
def print_board(board):
    print('   0 1 2 3 4 5 6 7 8 9 10 11 12 13 14')
    print(' ------------------------------')
    for i in range(15):
        print('{}|'.format(i), end='')
        for j in range(15):
            print('{}|'.format(board[i][j]), end='')
        print('\n ------------------------------')

# 判断是否下满了棋子
def is_full(board):
    for i in range(15):
        for j in range(15):
            if board[i][j] == ' ':
                return False
    return True

# 判断是否胜利
def is_win(board, row, col, player):
    # 水平方向
    count = 0
    for i in range(col-4, col+5):
        if i < 0 or i >= 15:
            continue
        if board[row][i] == player:
            count += 1
            if count == 5:
                return True
        else:
            count = 0
    
    # 垂直方向
    count = 0
    for i in range(row-4, row+5):
        if i < 0 or i >= 15:
            continue
        if board[i][col] == player:
            count += 1
            if count == 5:
                return True
        else:
            count = 0
    
    # 左上到右下方向
    count = 0
    for i in range(-4, 5):
        r = row + i
        c = col + i
        if r < 0 or r >= 15 or c < 0 or c >= 15:
            continue
        if board[r][c] == player:
            count += 1
            if count == 5:
                return True
        else:
            count = 0
    
    # 右上到左下方向
    count = 0
    for i in range(-4, 5):
        r = row + i
        c = col - i
        if r < 0 or r >= 15 or c < 0 or c >= 15:
            continue
        if board[r][c] == player:
            count += 1
            if count == 5:
                return True
        else:
            count = 0
    
    return False

# 玩家下棋
def player_move(board):
    while True:
        row = int(input('请输入行号(0-14): '))
        col = int(input('请输入列号(0-14): '))
        if row >= 0 and row < 15 and col >= 0 and col < 15 and board[row][col] == ' ':
            board[row][col] = 'X'
            break
        else:
            print('输入无效，请重新输入！')

# AI下棋
def ai_move(board):
    while True:
        row = random.randint(0, 14)
        col = random.randint(0, 14)
        if board[row][col] == ' ':
            board[row][col] = 'O'
            break

# 主函数
def main():
    board = init_board()
    print_board(board)
    
    while True:
        player_move(board)
        print_board(board)
        if is_win(board, row, col, 'X'):
            print('恭喜你，你赢了！')
            break
        
        if is_full(board):
            print('平局！')
            break
        
        ai_move(board)
        print_board(board)
        if is_win(board, row, col, 'O'):
            print('很遗憾，你输了！')
            break
        
        if is_full(board):
            print('平局！')
            break

if __name__ == '__main__':
    main()

这个代码实现了简单的五子棋人机对战，玩家执黑棋，AI执白棋。玩家通过输入行号和列号来下棋，AI则随机选择一个空位置下棋。游戏在玩家或AI获胜、棋盘下满时结束。
