用python写一个五子棋

好的，以下是一个简单的 Python 五子棋代码示例：

import numpy as np

# 棋盘大小
BOARD_SIZE = 15

# 棋盘数组
board = np.zeros((BOARD_SIZE, BOARD_SIZE), dtype=int)

# 玩家
BLACK = 1
WHITE = -1

# 当前玩家
current_player = BLACK

# 判断是否能落子
def is_valid_move(row, col):
    if row < 0 or row >= BOARD_SIZE or col < 0 or col >= BOARD_SIZE:
        return False
    if board[row][col] != 0:
        return False
    return True

# 落子
def play_move(row, col):
    global current_player
    if is_valid_move(row, col):
        board[row][col] = current_player
        current_player = -current_player
        return True
    else:
        return False

# 判断胜负
def check_win():
    for i in range(BOARD_SIZE):
        for j in range(BOARD_SIZE):
            if board[i][j] == 0:
                continue
            if j + 4 < BOARD_SIZE and board[i][j] == board[i][j+1] == board[i][j+2] == board[i][j+3] == board[i][j+4]:
                return board[i][j]
            if i + 4 < BOARD_SIZE and board[i][j] == board[i+1][j] == board[i+2][j] == board[i+3][j] == board[i+4][j]:
                return board[i][j]
            if i + 4 < BOARD_SIZE and j + 4 < BOARD_SIZE and board[i][j] == board[i+1][j+1] == board[i+2][j+2] == board[i+3][j+3] == board[i+4][j+4]:
                return board[i][j]
            if i + 4 < BOARD_SIZE and j - 4 >= 0 and board[i][j] == board[i+1][j-1] == board[i+2][j-2] == board[i+3][j-3] == board[i+4][j-4]:
                return board[i][j]
    return 0

# 打印棋盘
def print_board():
    for i in range(BOARD_SIZE):
        for j in range(BOARD_SIZE):
            if board[i][j] == BLACK:
                print('●', end=' ')
            elif board[i][j] == WHITE:
                print('○', end=' ')
            else:
                print('＋', end=' ')
        print()

# 游戏循环
while True:
    print_board()
    row = int(input("请输入行数："))
    col = int(input("请输入列数："))
    if play_move(row, col):
        result = check_win()
        if result == BLACK:
            print("黑方胜利！")
            break
        elif result == WHITE:
            print("白方胜利！")
            break
    else:
        print("输入有误，请重新输入！")

以上代码使用 numpy 数组实现了五子棋的落子、判断胜负等功能，游戏循环中通过输入行数和列数来进行落子。你可以根据自己的需要进行修改和扩展。
