To get the sunrise and sunset times, weatherWHAT uses suncalc. To discover weather around the world using natural text ('Paris, France'), weatherWHAT uses geopy. Pillow, a fork of the Python Imaging Library (PIL) is used to draw data on the images.
If using 'venv', set your environment:
source venv/bin/activate
The install the dependencies with
pip install -r requirements.txt
To display the images on your computer, using the -d option, Pillow requires a viewer. Install Imagemagick:
sudo apt-get update && sudo apt-get install imagemagick
