![]() ![]() Serialize obj as a JSON formatted stream to fp (a. dump ( obj, fp, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan=True, cls=None, indent=None, separators=None, encoding="utf-8", default=None, sort_keys=False, **kw ) ¶ To create a JSON array from a Python list, use the json.18.2.1. In this section, we will cover how to create, read, and manipulate JSON arrays in Python. JSON arrays are equivalent to Python lists, and working with them is quite simple using the json module. We then use this function as the object_hook parameter when deserializing the JSON string. In this example, we define a custom person_from_dict() function, which takes a dictionary as input and returns a Person object. Print(person) # Output: Person(name=John, age=30, city=New York) Person = json.loads(json_string, object_hook=person_from_dict) ![]() # Deserialize the JSON string to a Person object using the custom deserialization method To load JSON data from a string, you can use the json.loads() function. In this section, we will discuss two common scenarios: loading JSON data from a string and reading JSON data from a file. Reading and parsing JSON data in Python is a straightforward process using the json module. How To Read and Parse JSON Data in Python If you don’t encounter any errors or exceptions, it means the json module is available on your system, and you can start using it to work with JSON data. To check if you have the json module available, simply open a Python shell or create a new Python script and try importing the module: import json As long as you have Python installed on your system, you should already have access to the json module. The json module is part of Python’s standard library, which means you don’t need to install it separately. So, let’s dive in and explore the world of JSON data manipulation in Python. We will also explore the use of json.dump and json.load functions for file operations, handling errors and exceptions, and using JSON pretty printing to improve readability.īy the end of this tutorial, you will have a solid understanding of how to work with JSON data using Python’s json module and will be able to apply these techniques to your own projects. We will cover various aspects of working with JSON data in Python, including reading and parsing JSON data, creating JSON objects from Python dictionaries, serializing and deserializing Python objects to and from JSON strings, handling JSON arrays, and using custom serialization and deserialization methods.

In this tutorial, we will focus on working with JSON data using Python’s built-in json module. It is a prevalent choice for exchanging data between web applications and servers or for storing configuration and settings data. ![]() JSON, short for JavaScript Object Notation, is a lightweight data interchange format that has become widely popular for its human-readable nature and ease of use with various programming languages. ![]()
