Python 3.9: Dictionaries
Welcome to another Python 3.9 tutorial video, this video is about Dictionaries.
Dictionaries are a data structure in Python that are very similar to associative arrays. They contain "keys" and "values." Each key is unique and the values can be just about anything.
Dictionaries are sets and they are defined with {} curly braces.
Before python 3.6 dictionaries were unordered, so it would print the dictionary in some random order. But python version 3.6+ have ordered dictionaries so you don't have to worry about that anymore.
