Listing SOAP Services In Python

If you found a WSDL, you could of course just read the XML and figure out what it's doing, or you can use the Python module zeep to do it for you:

$ python -mzeep http://www.dataaccess.com/webservicesserver/numberconversion.wso?WSDL

Zeep seems to be the best SOAP client for Python. It's written on top of python Requests, it's well documented, and works on both Python 2 & 3.
