Hi Craig, How about creating your own module that does this in __init__.py.
You could create a directory (Eg craig_init) and in that directory create the file __init__.py containing the following code: try: import libxml except: # Blah, blah, blah. A clever bit of code goes here! WARNING: I haven't checked this myself, but it appears to be the way that the Zope Database python code has been written. If you have the ZODB package installed take a look at "Lib\site-packages\Btrees\__init__.py". I'm sure there must be other examples of this as well.

Or should I solve it in another way? def import_xml: try: import libxml except ImportError,err: # handle the error return libxml libxml = import_xml() -- Craig Ringer -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
