Dictionaries are the Python programming language’s way of implementing data structures. A Python dictionary consists of several key-value pairs; each pair maps the key to its associated value.
For example, say you’re a teacher who wants to match students’ names to their grades. You could use a Python dictionary to map the keys (names) to their associated values (grades).
If you need to find a specific student’s grade on an exam, you can access it from your dictionary. This lookup shortcut should save you time over parsing an entire list to find the student’s grade.
