Finding user's home dir
Could you explain a little more clearly what the problem is? In the
implementation of expanduser in Python 2.3.4, it uses the value of HOME env var
if it exists, otherwise, it uses HOMEDRIVE + HOMEPATH. I don't have access to
a Win 2K machine right now, but my recollection is that when I did, HOMEDRIVE
and HOMEPATH were set by Windows, so the right thing should happen.
Do you not have HOMEDRIVE + HOMEPATH set in your environment, e.g. if you open
a CMD.exe window?
When you say that it returned %USERPROFILE%, do you mean that it returned that
actual string, or the value of that env var?
Or is it that you want it to return the path to your My Documents directory,
which is not necessarily the same thing as %HOME%?
Thanks, Alec

It looks a lot like somebody who didn't test things out properly (the real administrator, not you), was trying to do the equivalent of "set home=%userprofile%" but managed to fail... if you do that at the command line or in a .CMD or .BAT file, it will expand the reference out and you'd have a "HOME=C:\Documents and Settings\whatever" just like you'd expect. Probably they put that in a dialog box somewhere without realizing it wouldn't be evaluated. (At least, I don't think environment variable substitution generally or ever has "lazy evaluation" semantics...) Now that I know how to do what Duncan described (thanks Duncan!), either approach works for me. Of course, whether I'm a likely eventual user of your particular program is an entirely different question. ;-) -Peter -- http://mail.python.org/mailman/listinfo/python-list

That's true :-D
But as I said in the other post os.environ["HOME"] doesn't work on my
Win2000 box.

If you look at ntpath.py (I think this is the 'path' module on
Windows 2000) in you Lib dir you'll see that expanduser does try
os.environ["HOME"]
So I'm not ignoring it, maybe it is redundant in my function.
The problem is that expanduser and user.home doesn't test if the value
returned is really a directory.

on my box it returns "%USERPROFILE%" ;-)

Re: Finding user's home dir
My own, less than perfect, way of finding the users home directory is like this: def personal_directory ( default = None ): pdir = None if sys.platform.startswith ( 'win' ): import _winreg reg = _winreg.ConnectRegistry ( None, _winreg.HKEY_CURRENT_USER ) pkey = _winreg.OpenKey ( reg, r"Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders" ) pdir = _winreg.QueryValueEx ( pkey, 'Personal' )[0] _winreg.CloseKey ( pkey ) _winreg.CloseKey ( reg ) else: pdir = os.getenv ( 'HOME' ) if not pdir: pdir = default return pdir -- Michael <[EMAIL PROTECTED]> http://kavlon.org -- http://mail.python.org/mailman/listinfo/python-list

You could just tell Windows to move your home directory location to
c:\users\peter and then all the environment variables will be set for you
automatically.
It probably varies wildly between Windows versions, but to assign a home
folder for a local user on XP go to Control Panel/Administrative
Tools/Computer Management/Local Users and Groups/Users, select your
account, right menu Properties, Profile tab, and edit the 'Home folder'
setting. Press F1 while editing the home folder location and see that at
least someone at Microsoft thinks c:\users\... is a sensible location.
