用python二维列表实现五子棋

下面是一个用 Python 实现的五子棋程序，使用二维列表来存储棋盘的状态：

# 初始化棋盘
board = [['+' for x in range(15)] for y in range(15)]

# 打印棋盘
def print_board(board):
    for row in board:
        print(' '.join(row))

# 判断是否胜利
def check_win(board, x, y):
    # 判断横向
    count = 1
    for i in range(1, 5):
        if x - i < 0 or board[y][x - i] != board[y][x]:
            break
        count += 1
    for i in range(1, 5):
        if x + i >= 15 or board[y][x + i] != board[y][x]:
            break
        count += 1
    if count >= 5:
        return True
    # 判断纵向
    count = 1
    for i in range(1, 5):
        if y - i < 0 or board[y - i][x] != board[y][x]:
            break
        count += 1
    for i in range(1, 5):
        if y + i >= 15 or board[y + i][x] != board[y][x]:
            break
        count += 1
    if count >= 5:
        return True
    # 判断左上到右下
    count = 1
    for i in range(1, 5):
        if x - i < 0 or y - i < 0 or board[y - i][x - i] != board[y][x]:
            break
        count += 1
    for i in range(1, 5):
        if x + i >= 15 or y + i >= 15 or board[y + i][x + i] != board[y][x]:
            break
        count += 1
    if count >= 5:
        return True
    # 判断左下到右上
    count = 1
    for i in range(1, 5):
        if x - i < 0 or y + i >= 15 or board[y + i][x - i] != board[y][x]:
            break
        count += 1
    for i in range(1, 5):
        if x + i >= 15 or y - i < 0 or board[y - i][x + i] != board[y][x]:
            break
        count += 1
    if count >= 5:
        return True
    return False

# 主循环
turn = 0
while True:
    # 打印棋盘
    print_board(board)
    # 询问玩家下棋位置
    if turn % 2 == 0:
        player = 'X'
    else:
        player = 'O'
    pos = input('Player %s, please enter your position (e.g. 1,2): ' % player)
    x, y = map(int, pos.split(','))
    if board[y][x] != '+':
        print('This position is already taken. Please choose another one.')
        continue
    # 下棋
    board[y][x] = player
    # 判断胜负
    if check_win(board, x, y):
        print_board(board)
        print('Player %s wins!' % player)
        break
    # 判断是否平局
    if turn == 224:
        print_board(board)
        print('It\'s a draw!')
        break
    # 轮换玩家
    turn += 1

注意，此处的实现只是一个简单的示例，并没有考虑很多情况，比如输入的坐标不合法等等。在实际开发中，需要根据具体需求进行修改和完善。
