Trouble installing modules/libraries and getting Notepad++ to show cyrillic letters

[snippsat]

https://photos.app.goo.gl/m9kWGqfVKjviSkhn6 - this is what I get whenever I try to install "os", but if it comes preinstall then, I shouldn't care about this error, correct?

You shall not install os as i posted it's a part of Python Standard Library(mean that all of this is already installed).

G:\div_code
λ python
Python 3.10.5 (tags/v3.10.5:f377153, Jun  6 2022, 16:14:13) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>>
>>> os.getcwd()
'G:\\div_code'
>>> exit()

Run cmd as Administrator

Ok

However I still can't get cyrillic to work, and I am not sure why:

You can not use single \ in path because of escape character.

>>> path = 'C:\Users\Tom\foo'
  File "<interactive input>", line 1
    path = 'C:\Users\Tom\foo'
                             ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

Fix all of these ways works.just put r(raw string) is the easiest way,

>>> path = r'C:\Users\Tom\foo'
>>> path
'C:\\Users\\Tom\\foo'
>>> 
>>> path = 'C:\\Users\\Tom\\foo'
>>> path
'C:\\Users\\Tom\\foo'
>>> 
>>> path = 'C:/Users/Tom/foo'
>>> path
'C:/Users/Tom/foo'
