Define PYTHONPATH such that Zope's "lib/python" is found.

python
	import Zope
	R= Zope.app() # the root object
	R.F1.F2.d     # traversal to "d"
	db= d.aq_base # unwrapped object
	dir(db)	      # "d"s attributes
	d.MHC	      # the bad MHC attribute, maybe inherited or acquired
	....

After you modified the ZODB, you need to commit your changes:

        get_transaction().commit()


For more information search Zope.org or the mailing list archives
for "get_transaction"...
