Python "TypeError: ' bool 对象不可调用”错误

Question

我正在编写一个简单的 Tic-Tac-Toe 游戏，它是玩家与电脑游戏，我不断收到“TypeError: 'bool' object is not callable”错误，我不明白为什么我会收到这些错误。我已经多次检查格式和语法，我看不出我的代码有什么问题，但我不断收到一些错误。这是我的代码。

    #board" is a list of 10 strings representing the board (ignore index 0).

问题出在这个函数中:

def isWinner(bo, le):
    return ((bo[7] == le and bo[8] == le and bo [9] == le) or
    (bo[4] == le and bo[5] == le and bo [6] == le)
    (bo[1] == le and bo[2] == le and bo [3] == le)
    (bo[7] == le and bo[4] == le and bo [1] == le)
    (bo[8] == le and bo[5] == le and bo [2] == le)
    (bo[9] == le and bo[6] == le and bo [3] == le)
    (bo[7] == le and bo[5] == le and bo [3] == le)
    (bo[9] == le and bo[5] == le and bo [1] == le))

您有一个 or在第一行之后，但在所有其他行中都没有。
