＆＃39;得分＆＃39;是我想要越过的变量。当MainGame（）运行时，得分+ 1每秒发生80次。比赛结束后，我想将比分改为StartScreen（）。基本上我希望看到球员在开场画面上得分。
答案 0 :(得分：2)
您必须在任何方法定义之外初始化变量得分。要访问变量并对其进行编辑，请使用关键字global。这告诉python您要访问的变量不是函数的本地范围。请阅读此处以获取有关正确使用全局变量的更多信息。 Using global variables in a function other than the one that created them

我不确定我是否抓住了所有分数的实例，但是如果我这样做了，那应该可行。得分定义在代码的顶部。在你的两种方法中，我在顶部键入全局分数。这让函数知道在其范围之外寻找变量得分。此外，导入应放在文件的顶部。无需始终导入相同的模块。
答案 1 :(得分：1)
使用全局变量将起作用。另一种方法是将分数传递给所有改变分数的函数并返回（至少）分数。
def some_func (score, otherstuff):
# do something with the inputs.
score += 1
return score, otherstuff.
答案 2 :(得分：0)
您可以做的是将变量完全放在函数之外，而不是将其保留在函数内部。这样，您拥有的所有功能都可以识别它。但是，如果您要从其他功能编辑score，只需将单词global score放在顶部，即表示您要编辑score的全球版本。< / p>
答案 3 :(得分：0)
管理分数的另一种方法是为您的游戏创建一个类，如果让所有改变分数的函数成为该类的成员是合理的。这可能是一个好的设计或一个糟糕的设计。如果采用这种方法，__init__函数应将self.score初始化为零。改变分数的函数应该只更新self-score的值。
