I think as a general rule with os.chdir()/os.getcwd() in Python apps. you can't
assume its value, it's a single piece of state shared across the entire app.
and all libraries, so really the best thing to do is not use it or rely on it.
Your result is not surprising, Leo is setting it between script calls.
Possibly Leo is doing this intentionally in a constructive way, setting the cwd
to the path implied by the node you're in (taking into account the location of
the .leo file and all parent @path directives. If you think about it a truly
Leonine shell representation might use the tree to represent directories.
For your application I'm not sure what the best approach might be. You could
sandwich your shell work between calls to some get_last_cwd() / save_last_cwd()
that stores a cwd in a uA per node or something.
Or perhaps a custom cd() function that does both get_last_cwd() and
save_last_cwd() at once, saves having to remember to use the other functions.

Subject: Re: Leo's HOME directory
I'll use this thread because it seems relevant. I'm trying to do some
experiments using Leo as a shell. Amongst other things I'm trying to change
this current working directory. I have a small node script:
@language python
import os
os.chdir("..")
g.es(os.getcwd(), color="green")
Perhaps naively I expected the log to show that I keeping dropping down a
level, as it would in a interactive python session. Unfortunately the output is
the same each time.
Any suggestions on changing the working directory? Or suggestions on
alternatives to keeping track of working directory in scripts.

I have no recollection of 2008 :-)
What's the alternative way to explicitly specify a different HOME directory
than the OS default?
According to lm.computeHomeDir, the home directory is
os.path.expanduser("~")
There is a comment in Leo's code that Windows searches the HOME, HOMEPATH and
HOMEDRIVE environment vars. Full details here. (Search for expanduser on this
page).
