Project Structure

We will roughly use the following simple structure for our application:

weather/
├── cli.py
├── client/
│  ├── protocol.py
│  ├── client_1.py
│  └── client_2.py
├── container.py
└── http.py

We have a file for each of our interfaces to the outside world (cli.py for our commandline interface and http.py for our HTTP server).

Our business logic lives in the client/ directory, where we define the central protocol for getting the data in protocol.py and one for each specific client. There is nothing stopping you from putting all of the business logic on one file, but separating them better shows their shared structure.

Finally we glue everything together in container.py, where all our diy Specifications and Containers are configured. These are then used in cli.py and http.py to retrieve pre-configured services that implement our business logic.
