Description:
A program to generate weather reports using the OpenWeatherMap API. Reports are generated for the current day and the following 3 days. OWM provides forecast data for free API keys only in the format of 5 day / 3 hour forecasts. This program calculates the averages over these reports and generates daily reports from the data. Forecasts are displayed in accordance with the local timezone of the system. Created as a school project with a focus on testing and mocking.
