How can I interact with Eclair from Python?
This might not be a satisfying answer but if you look at the eclair git repo and their Wiki you will find that the eclair API is a JSON API and is exposed via http and web sockets and can be queried with regular http requests.

If you look at the c-lightning python client it is a tool that talks via a unixDomainSocket to the exposed lightningd api. So I guess you could in a smilar way quickly create a python wrapper to be able to talk to eclair. 

It seems to me that currently no one has bothered to do so.
