Django Weather API
I used the MetaWeather API to fetch weather data. It can fetch historical weather data as well as up to a five day forecast.
I created an abstract base class to fetch weather so that it can easily be replaced by a different provider or a mock. Replace the WEATHER_CLASS settings value with "api.tests.mock_weather.MockWeather" to use a mock weather class instead.
Files of note:
weathermodule that contains the abstract base class,Weather, and other useful classes.metaweathermodule that contains the MetaWeather specific code.- Tests for weather fetching code.

Django might warn you to run migrations, but there's no need to set up a database or run migrations because we're not currently storing anything in a database.
