Save Python Dictionary as JSON

How can we save a Python dictionary as a JSON file?

To save a Python dictionary as a JSON file, you can use the json library and define a function that takes a dictionary and a filename as inputs.

Using the json Library

Python provides a built-in json library that allows you to work with JSON data. This library includes functions for encoding and decoding JSON data, making it easy to convert Python objects such as dictionaries into JSON format.

Defining a Function

To save a Python dictionary as a JSON file, you can define a function that takes the dictionary and filename as parameters. Within this function, you can use the json.dump() method to write the dictionary data to the specified file in JSON format. Here is an example of how you can define and use a function to save a Python dictionary as a JSON file: ```python import json def save_dictionary_as_json(dict, filename): with open(filename, 'w') as file: json.dump(dict, file, sort_keys=True) ``` In this example, the save_dictionary_as_json function takes two parameters: a dictionary (dict) and a filename. It then opens the file specified by the filename in write mode and uses the json.dump() method to write the dictionary data to the file in JSON format. The sort_keys=True option is included to ensure that the keys in the JSON output are sorted. By using the json library and defining a function like the one shown above, you can easily save a Python dictionary as a JSON file. This can be useful for storing data in a format that is easily readable and shareable with other programs or users.
