我正在尝试创建一个永远不会输的井字游戏 AI。我的代码有时有效，但其他时候不起作用。有时它会找到最佳移动并正确打印出来，但有时它会失败。例如，一旦 AI 占据中心，如果您按 9 并占据右上角，那么 AI 将占据左上角。然后，如果您选择右下角，AI 将选择左侧中间的瓷砖，然后如果您选择右侧的中间瓷砖，那么您将获胜。我希望人工智能采取中间的权利来阻止你获胜。我是一名初学者程序员，所以如果代码没有以最佳方式编写，请原谅。这是为什么？另外，您能否详细说明您的解释，以便我了解出了什么问题？代码如下：
the_board = {'7': ' ', '8': ' ', '9': ' ',
'4': ' ', '5': ' ', '6': ' ',
'1': ' ', '2': ' ', '3': ' '}
def print_board(board):
print(board['7'] + '|' + board['8'] + '|' + board['9'])
print('-+-+-')
print(board['4'] + '|' + board['5'] + '|' + board['6'])
print('-+-+-')
print(board['1'] + '|' + board['2'] + '|' + board['3'])
