Python：你如何让两个不同函数的两个值相等？

Question

所以我试图通过使用随机骰子在Python中编程一个二十一点游戏，我试图将玩家函数与经销商函数进行比较，但是我不知道如何与其他函数进行比较？如果你可以解释一下如何在一个函数中创建一个局部变量，这个局部变量等于另一个函数中的另一个局部变量，那将是非常值得赞赏的。代码是用于如果你只是想看看我想要做什么，它没有完成。

玩二十一点骰子的程序。

    the player's total score and whether the 
    player hit Blackjack, respectively.

Answer 1

您不能在函数之间直接共享局部变量。您的实际选择是返回值，设置全局变量，传入要修改的可变对象以包含数据，或者重写为使用保留值作为属性的类。

Answer 2

当函数被调用时，您可以使用全局变量并从函数内部设置它们的值。这样你就可以访问其他函数的值。
