给我一个黑白棋人人对战Python代码

以下是一个简单的黑白棋人人对战的Python代码：

import numpy as np

# 初始化棋盘
board = np.zeros((8, 8))
board[3][3] = 1
board[4][4] = 1
board[3][4] = -1
board[4][3] = -1

# 定义落子函数
def place(board, player, row, col):
    if board[row][col] != 0:
        return False
    directions = [[-1, 0], [1, 0], [0, -1], [0, 1], [-1, -1], [1, 1], [-1, 1], [1, -1]]
    other_player = -player
    to_flip = []
    for d in directions:
        r, c = row, col
        r += d[0]
        c += d[1]
        if r < 0 or r >= 8 or c < 0 or c >= 8:
            continue
        if board[r][c] == other_player:
            r += d[0]
            c += d[1]
            if r < 0 or r >= 8 or c < 0 or c >= 8:
                continue
            while board[r][c] == other_player:
                r += d[0]
                c += d[1]
                if r < 0 or r >= 8 or c < 0 or c >= 8:
                    break
            if r < 0 or r >= 8 or c < 0 or c >= 8:
                continue
            if board[r][c] == player:
                while True:
                    r -= d[0]
                    c -= d[1]
                    if r == row and c == col:
                        break
                    to_flip.append([r, c])
    if len(to_flip) == 0:
        return False
    board[row][col] = player
    for r, c in to_flip:
        board[r][c] = player
    return True

# 定义判断是否有合法落子点的函数
def has_legal_moves(board, player):
    for row in range(8):
        for col in range(8):
            if board[row][col] == 0:
                if place(board, player, row, col):
                    return True
    return False

# 定义判断胜负的函数
def get_winner(board):
    black_score = np.sum(board == 1)
    white_score = np.sum(board == -1)
    if black_score > white_score:
        return 1
    elif white_score > black_score:
        return -1
    else:
        return 0

# 定义主函数
def main():
    player = 1
    while has_legal_moves(board, player):
        print(board)
        print("Player", player)
        row = int(input("Enter row: "))
        col = int(input("Enter column: "))
        if place(board, player, row, col):
            player = -player
    print(board)
    winner = get_winner(board)
    if winner == 1:
        print("Black wins!")
    elif winner == -1:
        print("White wins!")
    else:
        print("Tie!")

if __name__ == '__main__':
    main()

这个代码实现了一个简单的黑白棋人人对战游戏，玩家可以通过输入行和列来落子，程序会自动判断是否合法，并进行翻转。最后，程序会输出胜利者或者平局。
