How to figure out where is my python installed using OS or Sys

Question

Is there a way to find out where is my python installed using OS?

Well i know that if we open a shell and run this:

import os
os.getcwd()

it will work but can we do this in idle too ?

when its saved on desktop for example ?

actually I'm looking for this output for example:

C:\Users\user\AppData\Local\Programs\Python\Python37

>>> print sys.prefix
