我知道我刚才刚刚问了另一个问题，但是我有点卡住了。我的游戏是关于您在三个空间之间移动以躲避速度不同的正方形。 “速度”文本标签（我不知道该怎么称呼）更新正常（并且当块到达屏幕底部时更新），但是高分文本标签（高分从泡菜中加载） 。如果您想知道泡菜文件中是否已经加载了高分。它不是空的。

答案 0 :(得分：0)
这是一个可变范围的问题。在将score和highScore都定义为全局变量（在任何函数之外）的同时，您随后在highScore和saveScore()中为loadScore()分配了一个值。执行分配时，Python会将变量解释为函数的本地变量。 saveScore()的最终结果仍然有效。实际上，您可以为score分配一个值，并查看它是否正确保存。但是，当您使用loadScore()时，将从文件中读取值，然后将其分配给highScore，但仅在函数的本地范围中：一旦函数完成，价值丢失了。
两种解决方法。
最简单的方法是在global highScore函数内部简单地添加一个loadScore()语句，这样就不会产生歧义。可以，但是不建议这样做。
第二种也是最合适的方法是重新构建变量范围，并进行如下更改：
saveScore()接受参数，这是您要保存的值loadScore()在return语句中返回加载的值score和highScore的跟踪，并在适当时保存/加载另外，为获得更好，更完整的解释，请查看Global, Local and nonlocal Variables上的本教程。希望这会有所帮助。
