Not that I'm especially interested in weather :-), but the goal was to play with the following concepts in Python:

• Dependencies management via Pipenv
• Unit tests with pytest
• Parallel operations via asyncio and aiohttp
• "Domain" and "Web API" logic handled separately, in a DDD way
• Dependency injection, via scute, a Python clone of PHP's Pimple
• Minimalist JSON API with Flask
  (could be interesting to start with something even more minimalistic like Roll, as I don't need Jinja for a JSON API)
• "Closer to real world" JSON API with Django
  The more I work with Django, the more I realise that Symfony basically copied lots of Django features: templating system, Forms, etc :-)

Even if it's a dummy and very small project I have been able to apply most of the best practices I use for my usual domain of expertise (Symfony): DDD-like development, dependency injection, Makefile, Docker Compose...

I really enjoy Python! Clear syntax, rich stdlib, functions named arguments, type hinting, coroutines... Great stuff! :-)
