What is the difference between sys and os.sys in python? I have seen many projects using sys when they have imported os. When I tried dir(sys) and dir(os.sys) they had same functions and their output was same.
python中sys和os.sys有什么区别？我已经看到很多项目在导入os时使用sys。当我尝试dir（sys）和dir（os.sys）时，它们具有相同的功能，并且它们的输出相同。
I often see code using sys.exit like this, rather than using os.sys.exit, but both do the same thing.
我经常看到像这样使用sys.exit的代码，而不是使用os.sys.exit，但两者都做同样的事情。
import os
import sys
sys.exit()

os.sys is os's "private" name for sys; Python does not hide imports performed in another module. You should not depend on its existence, and should instead import sys directly yourself.
os.sys是os的sys的“私有”名称; Python不会隐藏在另一个模块中执行的导入。你不应该依赖它的存在，而应该自己直接导入sys。
