Hi,
currently there is no Python Agent available for any of the supported CA APM versions.
An EPAgent can definitely be used to retrieve data from accessible sources (like log files), but I'm not aware of any pre-configured EPAgents specialized on Python.
I would urge you to create an idea here in the community and describe the needs and expectations of such an agent.
It might not be the answer you were hoping for, but I still hope this information helps.
BR,
Stig
