Yes, but this is still better than hasattr() which eats all exceptions. I think eating AttributeErrors is fine because to the user of 'ob', it would seem that ob.attr wouldn't exist anyway if it threw an AttributeError (even if that exception was about something else, it's still an AttributeError). I suggest doing marker = object() return getattr(ob, name, marker) is marker rather than return hasattr(ob, name) _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
