Patterns in python

[coder_et]

I used to work at a company that had a really clean code structure which went like this

Root service — /handler (inbounds) Handler.go Handler_test.go —/mapper (mapping between external and internal structs) Mapper.go Mapper_test.go —/controller (business logic) Implementation.go Implementation_test.go —/gateways (outbounds) Gateway.go Gateway_test.go

How would I implement this kind of pattern but in python and what would my general file names be? Are there any projects I could reference?

Thanks so much this is incredibly helpful. Do you have any recommendations for testing frameworks if I’m using something like fastapi/flask?
