请用Python写个五子棋代码

当然可以！以下是一个简单的五子棋代码示：

# 定义棋盘大小
_SIZE = 15

# 初始化棋盘
board = [[0] * BOARD_SIZE for _ in range(BOARD_SIZE)]

# 定义棋子类型
EMPTY = 0
BLACK = 1
WHITE = 2

# 定义当前下棋方
current_player = BLACK

# 判断是否胜利
def check_win(row, col):
    directions = [(1, 0), (0, 1), (1, 1), (1, -1)]
    for dx, dy in directions:
        count = 1
        i, j = row + dx, col + dy
        while i >= 0 and i < BOARD_SIZE and j >= 0 and j < BOARD_SIZE and board[i][j] == board[row][col]:
            count += 1
            i += dx
            j += dy
        i, j = row - dx, col - dy
        while i >= 0 and i < BOARD_SIZE and j >= 0 and j < BOARD_SIZE and board[i][j] == board[row][col]:
            count += 1
            i -= dx
            j -= dy
        if count >= 5:
            return True
    return False

# 下棋函数
def move(row, col):
    if row < 0 or row >= BOARD_SIZE or col < 0 or col >= BOARD_SIZE or board[row][col] != EMPTY:
        return False
    board[row][col] = current_player
    if check_win(row, col):
        print("黑棋胜" if current_player == BLACK else "白棋胜")
        return True
    return False

# 游戏循环
while True:
    # 打印棋盘
    for i in range(BOARD_SIZE):
        for j in range(BOARD_SIZE):
            if board[i][j] == EMPTY:
                print("_", end=" ")
            elif board[i][j] == BLACK:
                print("X", end=" ")
            else:
                print("O", end=" ")
        print()
    # 获取玩家输入
    row = int(input("请输入行号："))
    col = int(input("请输入列号："))
    # 下棋
    if move(row, col):
        break
    # 切换下棋方
    current_player = WHITE if current_player == BLACK else BLACK

这是一个简单的五子棋代码，可以在控制台中进行游戏。玩家需要依次输入行号和列号来下棋，程序会判断胜负并打印棋盘。注意，此代码只实现了基本功能，没有考虑规则限制、禁手等高级功能。
