Here is what the above code is Doing:
1. We’re creating a new SOAP client using the Zeep library.
2. We’re setting up the client to use the WSDL file from the SOAP service.
3. We’re calling the getCitiesByCountry method from the SOAP service, passing in the country code “US” as a parameter.
4. We’re printing out the results of the SOAP call.
