Tracking airplanes

Hey so I know about nothing as it comes to coding. Im a plane spotter and I’m looking to make a program that alerts me with discords bot api if a plane flies over my city. I’m looking to do this with python and a raspberry pi and using the data of adsbexchange read something about it on adsbexchange.com/data/rest/api-samples/ so I don’t really understand any of this is there someone that can help me?
