如何在不必重新启动程序的情况下更新哪个资产文件夹以使代码具有访问权限？

Question

我目前正在为自己的练习开发一个非常简单的游戏

我有3个正在处理的文件：

我所有的主代码都存储在这里

main.py 

我的大部分函数都存储在这里。它也是我为我的游戏加载所有图形的地方

data.py 

跟踪当前加载的主题，并跟踪来自2个不同保存文件的数据

save_file.txt

下面是游戏流程的大致情况

[main.py]
imports data
    [data.py]
     checks save_file.txt line[0] 
     if line[0] == 1
         load theme_1
     elif line[0] == 2
         load theme_2
    if theme_1 is loaded
        Assets1 folder is called on to load in graphics
    elif theme_2 is loaded
        Assets2 folder is called on to load in graphics

让我们假设程序以默认为1的主题开始。现在，每当我的程序加载图片时，它都将是Assets1文件夹中的版本。但是，如果我写入theme.txt将1改为2，然后继续玩游戏，图形仍然会从Assets1调用，直到游戏关闭并重新执行

我怎样才能在不让用户重新开始他们的整个游戏的情况下让它更新呢。或者，是否有一个python命令将关闭程序并重新执行它

谢谢 以下是实际代码（如果有帮助）：
