https://doc.dovecot.org/configuration_manual/authentication/dict/
There is an example script done in perl at the bottom of the page.
Maybe it can give you hints as to the format needed for a python script.


On the same page it also says:
When given a proxy URL the Dict backend speaks a simple protocol over a 
UNIX socket.
The protocol is defined in src/lib-dict/dict-client.h
