What is the primary use of the JSON module in Python?

The primary use of the JSON module in Python is to parse JSON data and convert it to or from Python data types. JSON, which stands for JavaScript Object Notation, is a lightweight data interchange format that is easy for humans to read and write, as well as easy for machines to parse and generate.

The JSON module provides methods like json.dump(), json.dumps(), json.load(), and json.loads() that facilitate the conversion between JSON strings and Python objects. This makes it straightforward to read JSON data from files or strings and transform it into Python dictionaries or lists, as well as to take Python data structures and convert them into JSON format for storage or communication.

Understanding this functionality is crucial when working with web APIs, data serialization, or any scenario that requires exchanging data in JSON format, which is a widely used format in web applications due to its simplicity and compatibility with various programming languages.
