What is json : JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is widely used for representing structured data and exchanging information between different systems. JSON data consists of key-value pairs or arrays, which can be nested to represent complex structures.

Working with json in Python programming language : Python provides built-in support for working with JSON data through the json module. It offers functions to serialize Python objects into JSON strings (encoding) and deserialize JSON strings into Python objects (decoding). This makes it convenient to exchange data between Python programs and external systems using the JSON format.

How to read a json file in Python programming language : Reading a JSON file in Python involves loading the JSON data from a file into a Python object. The json module's load() or loads() functions can be used to achieve this. Using these functions, developers can retrieve the JSON data stored in a file and access its contents as a Python object for further processing or analysis.

How to write data to a json file in Python programming language : To write data to a JSON file in Python, the json.dump() or json.dumps() functions are used. These functions serialize Python objects as JSON-encoded data and write it to a file. This allows developers to persist Python data structures to a file in the JSON format, making it readable and shareable.

How to append data to json file in Python programming language : Appending data to a JSON file in Python requires a slightly different approach. First, the file needs to be opened in a mode that allows appending, such as 'a' or 'a+'. Then, the existing JSON data is loaded into a Python object, updated with the new data, and written back to the file using json.dump(). This ensures that new data is added without overwriting the existing content.

Dump json data in Python programming language : The json.dump() function in Python is used to serialize Python objects as JSON data and write it to a file-like object. This function takes the Python object and the file-like object as parameters, converting the object to a JSON string and storing it in the file. It simplifies the process of saving Python data as JSON.

Load json data in Python programming language : Loading JSON data in Python involves using the json.load() function to deserialize a JSON-encoded string or file-like object into a Python object. This function takes the JSON string or file-like object as input and returns the corresponding Python object. It allows developers to retrieve and work with the JSON data in their Python programs.

PrettyPrint JSON Data in Python : Python's json module provides the json.dumps() function with the indent parameter to pretty print JSON data. By setting the indent value to a specific number of spaces, the output JSON string will be formatted and indented for improved readability. This is helpful when displaying or debugging JSON data in a more human-friendly format.
