What is the best way in Python version 2.x to read/get Windows (nt/2000/xp)

Thanks for the help!

first install Mark Hammond's excellent Win32all extensions:
http://starship.python.net/crew/mhammond/

Then it's really simple:

import win32api
win32api.GetEnvironmentVariable('path')

'c:\\bin;c:\\Python23\\scripts;C:\\WINDOWS\\system 32;C:\\WINDOWS;C:\\WINDOWS\\System32\\Wbem;C:\\PRO GRA~1\\COMMON~1\\Ulead
Systems\\MPEG;C:\\Program Files\\Common Files\\Ulead Systems\\MPEG'

If you need to get the list of system environment variables and the (separate) list of user environment variables, you'll have to read the following registry settings:

System: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Environment

User: HKEY_CURRENT_USER\Environment

You can use the win32api functions RegConnectRegistry, RegOpenKey, RegQueryValue etc. for these.
