You could have a look at the PyPI packages "dm.zope.rpc"
and "dm.zope.rpc.wsdl_suds". They provide a middleware
to support protocol independent web services (for the
"Zope" application server). Together, they support
XML-RPC, JSON-RPC and WSDL decribed SOAP web services.
As you are likely not using Zope, you probably cannot use
these packages directly but you may get some ideas how
to create such a middleware for your web framework.
Python (from 2.6 on) has "json" support. Thus converting
a dict to "json" is simple ("json.dumps").
"dm.zope.rpc.wsdl_suds" abuses "suds" to parse the WSDL
and generate appropriate SOAP responses from a dict.
Alternatively, you might use "PyXB" for that.
You could also have a look at "Spyne" (formerly known (among others)
as "rpclib"). I think (but am not sure) that it targets
your use case for the "twisted" environment.
