[Zope] Completion for zope script

Hello, Is there somewhere an editor that allow me to have the completion when I am writting my python script for zope? I am fighting with boa - constructeur in order to get it working with my installation but till now without any success. Thus i have added the following lines in "Explorer.gtk.cfg": zope = {Localhost: {'host': '127.0.0.1', 'httpport':'9080', 'ftpport': '8021', 'username': 'admin', 'passwd': '123', 'path':'/' , 'name': '','localpath':''}} and when I launch boa I get this error message: - Transport category not added: name 'Localhost' is not added any suggestion either to solve my boa pb or to point me to another editor with a completion for zope are more than welcome. thank you for your help
