In Python, dictionaries are data storage objects that use a key to retrieve a value. Think of your cell phone contact list or phone book. We look for the name of the person, the key, and their phone number is the value. Dictionaries are incredibly useful when storing and sorting data. We used a dictionary in our for loop project which saw RSS news feeds used to generate content on a web page.
We’re going to go through how to create, update and delete keys and values inside of a dictionary and then use a dictionary in a real world project where we create a notification system using Python and nfty.sh.
