Reading environment variables in ArcPy?

[المشرف العام]

I have a script that tries to read from the arc environment using

import arcpy tolerance = arcpy.env.XYTolerance as recommended here: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002z0000000w000000

Alas tolerance always ends up as None. Even when I set it explicity in the Environments... part of the script dialog box.

Is this a bug?
