Zeep

A fast and modern Python SOAP client. Compatible with Python 3.7, 3.8, 3.9, 3.10, 3.11, and PyPy. Build on top of lxml and requests. Support for Soap 1.1, Soap 1.2 and HTTP bindings. Support for WS-Addressing headers. Support for WSSE (UserNameToken / x.509 signing) Support for asyncio via httpx. Experimental support for XOP messages. Zeep inspects the WSDL document and generates the corresponding code to use the services and types in the document. This provides an easy-to-use programmatic interface to a SOAP server. Parsing the XML documents is done by using the lxml library. This is the most performant and compliant Python XML library currently available. This results in major speed benefits when processing large SOAP responses. The SOAP specifications are unfortunately really vague and leave a lot of things open for interpretation.
