WCF and Python

Question

Is there any example code of a cpython (not IronPython) client which can call Windows Communication Foundation (WCF) service?

Answer 1

TL;DR: For wsHttpBinding (SOAP 1.2) use zeep

In case someone is having trouble using suds (or suds-jurko for that matter) with WCF and wsHttpBinding (which is SOAP 1.2):

• suds is pretty much dead (can't even pip install it on python 3)
• suds-jurko seems kind-of dead. The 0.6 release has a very annoying infinite recursion bug (at least on the WSDL exposed by our service) which is fixed in the tip but that's not released and it's been 1.5years (at time of this writing in Feb'17) since the last commit.
  It works on python 3 but doesn't support SOAP 1.2. Sovetnikov's answer is an attempt to get it working with 1.2 but I haven't managed to make it work for me.
• zeep seems to be the current way to go and worked out of the box (I'm not affiliated with zeep, it just works for me and I spent several hours banging my head against a brick wall trying to make suds work). For zeep to work, the WCF service host configuration must include under the wsHttpBinding node Actually zeep seems to support username and signature (x509) based WS-SE but I haven't tried that so can't speak to any problems around it.
