Modify the module import to use try except.

This issue will track if I"m already using try except if the module is already imported or not. It will avoid importing the same module over and over again since python does not let you do ifndef you have to wrap it in a try except block.

try:
module
except NameError:
import module

Do this for each module as it's being imported to see if we've not already gotten it. This way we can check if it's already there. This should've already been covered but SO guys didn't tell me how to do this which is what I wanted to do but oh well my hack needs to be fixed.

在代码库中找到所有模块导入，并将其替换为 try-except 块以避免重复导入。首先在 Python 文件中搜索 'import' 语句。更改后，运行游戏以确保其仍能正常工作。该 issue 未指定要修改哪些文件。
