A Python “dictionary” is very similar conceptually to what we know a dictionary to be in everyday usage. An English dictionary at its simplest is a collection of words with their definitions. The KEY is the word, the definition is the VALUE.
The Python dictionary data structure is a collection of KEY-VALUE pairs.
In this lesson, you will make use of a Python dictionary to create, sort, and display key-value data items as they might be presented in a medical setting.
