windows - python 文件读写 权限 permission denied

Question

我写了一个python小工具，安装在C:\Program Files (x86)\appname目录下,可是无法创建和读写文件，出现permission denied错误提示。
之前程序是可以在C:\Users\XXX\AppData\Local\VirtualStore\Program Files (x86)创建文件的，因为改了一大堆东西，而且代码也很长，就不贴代码了。
如何做才能在C:\Users\XXX\AppData\Local\VirtualStore\Program Files (x86)\appname创建文件，不关闭UAC，不使用管理员权限。

就像这样的代码：

# -*- coding: utf-8 -*-
with open("a.txt","w")as f:
    pass

Answer 1

It has something to do with the directory. This directory under Windows requires administrator rights. You can go to other directories such as the E:AC directory to operate files

Answer 2

Please add it.
I hope to use UAC virtualization, but this is a practice that Windows does not advocate. The question asks about the reasons and solutions for UAC virtualization failure. I was able to virtualize successfully before, but I don't know why it failed.
Also gives the recommended method for windows. Create files in other directories. Use os.getenv('ALLUSERSPROFILE')或者os.environ.get('ALLUSERSPROFILE')获取系统环境变量，然后构造路径。相关的变量还有LOCALAPPDATA和APPDATA to correspond to different directories. Perhaps with a suitable method, this problem will disappear. It is better to obtain system variables and write them into files instead of creating folders on the C drive or other drives. What if there is no other DEF drive letter, or the system drive letter is not the C drive? The program should not be written to death. It is best to follow Microsoft's suggestions and everyone's agreed practices. Finally, I lament that segmentfault is not active enough. The questions I asked are basically self-asked and answered. Let me complain again, the text editor is not easy to use.

You can divide directory permissions. If you must create files in this directory, give this folder writable permissions. Inheriting permissions depends on your needs
