In this section, we will learn how to work with the JSON data format, how to convert Python objects into the JSON data format, and how to convert them back to Python objects in Python 3.7.

JSON corresponds to the way in which objects are defined in JavaScript. JSON is a standard way of representing simple objects, such as lists and dictionaries, in the form of text strings. Although it was originally developed for JavaScript, JSON is language-independent and most languages can work with it. It's lightweight, yet flexible enough to handle a broad range of data. This makes it ideal for exchanging data over HTTP, and a large number of web APIs use this as their primary data format.
