Not quite

The interpreter inherits the command shell's history function:
Open a cmd window and then a Python session. Do some stuff.

Ctrl-Z to exit to the surrounding cmd window.
Do some random cmd stuff: dir, cd, etc.

Start a second Python session. up-arrow etc. will bring back
the previous Python session's commands (and not the ones you
entered in the surrounding shell)

Obviously this only applies when an underlying cmd session
persists -- if you simply start Python from Start > Run
twice the command history will not persist between sessions.
