Is there any way to set Python IDLE's interactive shell indentation width to 2 spaces instead of its default?

Question

I'm not asking about Options > Configure IDLE > Fonts/Tabs > Indentation Width and setting that to 2. This only sets the indentation width within a file and not the indentation width for the interactive shell.

What Python IDLE file do I need to change to get 2-space spacing in the interactive shell?

I like to code with 2 spaces instead of 4 so not having the interactive shell also indent by the same spacing slows me down when transferring out of shell and into a file for example.

There is a solution!!! *1

Solution

go to idlelib (/lib/idlelib/) *2
open "pyshell.py"
go to class PyShell, __init__

there are 3 lines

self.usetabs = True
# indentwidth must be 8 when using tabs.  See note in EditorWindow:
self.indentwidth = 8

just change them to

self.usetabs = False
# indentwidth must be 8 when using tabs.  See note in EditorWindow:
self.indentwidth = 4 # you decide, lot of people prefer 2

P.S.

this will result in wierd looks:

>>> def f(x): # calculate x*abs(x)
    if x > 0: # it doesn't look it, but this is indented once
        return x*x # and this twice
    else:
        return -x*x

But I think it looks better then 8-spaces-tab indent

*1 I'm working with python 3.8 on windows 10, but this may work elsewhere

*2 depending where python is installed
step 1: find python (to me it is "C:\Programs\Python 3.8")
step 2: from there go to /lib/idlelib/
