python3 using qpid::proton with Solace pubsub+ broker

Hello all. Reading the doc., hum hum, I discovered the Solace Broker requires some values in the creation of a “sender” object . Those lines with the two “default” are compulsory and solve this (“rookie”) problem of credentials, I succeed to consume message from Solace using qpid::proton … ?



But my way forward is to use python solace binding , lightweight, more recent. Kind regards to all .
