JSON in Python | Tutorial #26. Python’s json module converts between JSON and Python objects using functions like dump() and load().

In Python, JSON (JavaScript Object Notation) is a popular format for data interchange, known for its simplicity and human-readability. JSON is used extensively to transmit data between a server and web applications, or to serialize and deserialize data structures in various programming contexts. Python provides robust support for working with JSON through the json module, which is part of the standard library.

The json module enables you to convert Python objects into JSON format and vice versa. This process is known as serialization (or encoding) and deserialization (or decoding). The primary functions in this module include json.dump(), json.dumps(), json.load(), and json.loads().

json.dump(obj, file_obj): This function writes a Python object obj to a file-like object file_obj in JSON format. It's useful for saving JSON data directly to a file.

json.dumps(obj): This function converts a Python object obj into a JSON-formatted string. It’s useful when you need a JSON representation of an object for transmission or storage.

json.load(file_obj): This function reads JSON data from a file-like object file_obj and parses it into a Python object. It’s commonly used for loading JSON data from files.

json.loads(s): This function parses a JSON-formatted string s and converts it into a Python object. It’s useful for handling JSON data received as a string from web responses or other sources.

Python's json module handles common data types such as dictionaries, lists, strings, numbers, and booleans, but it does not directly support more complex types like custom classes. To work with such types, you may need to define custom serialization methods.

Overall, JSON’s lightweight and easy-to-read structure makes it an ideal choice for data interchange, and Python’s json module offers a straightforward way to work with this format in your applications.
