Is there a way to call a pyscript from within some other automation or yaml script and make use of the output in that other script.

For many services you can use response_variable e.g

- service: weather.get_forecast
 data:
 type: hourly
 target:
 entity_id: weather.forecast_home
 response_variable: hourly_forecast

Is this possible in a pyscript or is there another approach other than using a helper with an input_text as I am doing now?
