I'm no windows user, but under unix a child process (which is created using
os.system) inherits the environment of its porent process as a copy - so
chtanges in the childs env don't affecth the parents one. Which is
probablpy a good idea, as ontherwise I'd be able to manipulate the calling
process in undesirable ways.

So I think you need some parsing to intercept a cd and change your current
working  dir using the os module.

Aren't there more shell like interactive pythons out there - ipython or so?
Look at them, they might be what you seem to be after here.
