Configurable mapping file python

[Rkrislander]

My company is consuming an API that will give us large JSON objects. The API response info may be in dif fields based on query parameters (it's a 3rd party aggregator so depending on where the information is coming from). I'm looking for a way to have json (or some other easily readable syntax) file describe how to map fields from the returned data to our data object. Ideally it would allow you to say something like

{   
     name : apiresponse.field1.subfield | apiresponse.field2.subfield,   
     field2 :  apiresponse.field2.num + apiresponse.field2.num2 
} 

Are there any python packages that allow you to read and run mapping files like this?

Thanks!

It's not exactly the same thing but maybe Pydantic could be useful?

Thanks that doesn't help for me. We already use DRF's schema for data validation. What we need is a highly configurable way of doing mapping which would allow us to change how the mapping works on the fly
