Json.dump()

As explained in A Pythonic Adventure: From Python basics to a working web app

The Python json.dump function serializes a Python object as JSON and writes the result to a file-like object.

How A Pythonic Adventure: From Python basics to a working web app covers it

How deep it goes

Explains the two required arguments, optional indentation, and file closing, but does not examine serialization internals.

Examples

Uses coffee orders, orders.json, a list of orders, and readable indent=4 output.

What it assumes

Assumes basic Python dictionaries and file opening while teaching the json import and file-writing workflow.

What you can do after

Apply it via Python’s json module to save dictionaries or lists as JSON files.

How it connects

Connects dictionaries, JSON, file objects, open(), close(), and json.load().
