There is nothing that plainly differentiates whether an environment variable is the system's or the current user's.
What you could do is: 1. Get the list of environment variables for the user the script is executing as. 2. Use the pywin32 extensions to access the registry key HKCU\Environment 3. Lookup the environment variables present in the list (Item 1) that appear as string values under HKCU\Environment. 4. The intersecting list belongs to the user, the rest can be surmised as belonging to the system environment. Thanks, --Kartic -- http://mail.python.org/mailman/listinfo/python-list
