Dictionaries store data in keyvalue pairs from "summary" of Python Programming by John M. Zelle
Dictionaries in Python are a very useful data structure that allow us to store data in a way that is efficient for easy retrieval. They work by associating keys with values, so that we can quickly look up a value based on its corresponding key. This is similar to how we might look up a word in a physical dictionary - we find the word we are looking for, and then see its definition right next to it. When we create a dictionary in Python, we specify both the keys and the values that we want to associate with each key. This allows us to store data in a way that is easy to access later on. For example, if we were creating a dictionary to store information about students, we might use the student's name as the key and their grade as the value. This way, we can ...
