There are two possibilities:
1. You don't care about ExtensionClass. You are importing
Persistence because that's what you imported in the past.
In this case, you should really use the persistent package
instead:
>>> from persistent import Persistent
>>> from persistent.list import PersistentList
>>> from persistent.mapping import PersistentMapping
2. You want your classes to be ExtensionClasses. In this case,
you need to install the ExtensionClass package
separately. ExtensionClass is no-longer included with ZODB3.
