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. In Python, working with JSON data is straightforward, thanks to the built-in json module.
This tutorial will guide you through the process of extracting and using data from JSON in Python. We'll cover reading JSON from a file, parsing it into Python objects, and accessing the data.
Before you can work with JSON in Python, you need to import the json module.
Assuming you have a JSON file named data.json, you can load its content into a Python object using the load function from the json module.
Now that you have loaded the JSON data into a Python object, you can access its values using standard Python syntax. JSON data is usually structured as dictionaries and lists.
If your JSON data contains nested structures like dictionaries or lists, you may need to iterate through them.
If you make changes to the Python object and want to save it back to a JSON file, you can use the dump function from the json module.
That's it! You've successfully learned how to extract and use data from JSON in Python. Feel free to adapt these examples to suit your specific use case.
