To write data to a JSON file in Python, you first need to import thejsonmodule. This module provides functions for encoding and decoding JSON data. You can use thejson.dump()function to write data to a file in JSON format. Here is a simple example that demonstrates how to write a dict...

Writing JSON to a file To write JSON to a file in Python, we can use json.dump() method. Example 4: Writing JSON to a file import json person_dict = {"name": "Bob", "languages": ["English", "French"], "married": True, "age": 32 } with open('person.txt', 'w') as jso...
