WSDL tools/problems (Salesforce.com)

[Dan]

Salesforce.com has what looks to be a nice SOAP interface (see
http://www.sforce.com) which I would like to access via Python.

I am currently trying to use the newest release of ZSI (1.4.1) to
process our Salesforce WSDL file but have run in to problems (see
below). *Any* suggestions on alternative approaches, or how to get
this approach to work will be appreciated.  Also please note, since I
am new to both Python and ZSI, that this is may be something really
obvious.

Thanks in advance,
Dan

Here is an example:

>>> from ZSI.wstools.WSDLTools import *
>>> w=WSDLReader()
>>> w.loadFromURL('http://gothamanalytics.com/Ex/enterprise.wsdl')
