Python-调用对象，直到对象返回true

Question

有没有一种方法可以调用self.bestSpot（...），直到返回True。我正在玩井字游戏，我希望computerTurn（）调用bestSpot（），直到bestSpots（）之一工作为止，此时计算机将轮到他，并且人类可以采取下一步行动。 / p>

def computerTurn(self):
    botPawn = self.getCurrentPlayerPawn()
    if botPawn == 'O':
        enemyPawn = 'X'
    elif botPawn == 'X':
        enemyPawn = 'O'

    while True:
        self.bestSpot(enemyPawn, 0, 1, 2)
        self.bestSpot(enemyPawn, 3, 4, 5)
        self.bestSpot(enemyPawn, 6, 7, 8)

def bestSpot(self, enemyPawn, num0, num1, num2):
    if self.placeHolder[num0] == enemyPawn and self.placeHolder[num2] == enemyPawn:
        self.playerTurn(str(num1))
    elif self.placeHolder[num0] == enemyPawn and self.placeHolder[num1] == enemyPawn:
        self.playerTurn(str(num2))
    elif self.placeHolder[num1] == enemyPawn and self.placeHolder[num2] == enemyPawn:
        self.playerTurn(str(num0))
    else:
        return(False)

def playerTurn(self, button_name):
    for i in self.buttons:
        if button_name == i.objectName() and int(button_name) in self.placeHolder:
            self.moves = self.moves + 1
            player = self.getCurrentPlayerPawn()
            self.buttons[int(i.objectName())].setText(player)
            self.placeHolder[:] = [player if x == int(i.objectName()) else x for x in self.placeHolder]
            self.buttons[int(i.objectName())].setEnabled(False)
            self.checkWin(player)
            self.changePlayer()
