Naturally we can use the json library to translate Python objects to JSON as well. This is especially useful in instances where you’re using a Python library to serve web pages, you would also be able to serve JSON. Let’s say we had a Python dictionary we wanted to save as a JSON file:

turn_to_json = {
  'eventId': 674189,
  'dateTime': '2015-02-12T09:23:17.511Z',
  'chocolate': 'Semi-sweet Dark',
  'isTomatoAFruit': True
}

We’d be able to create a JSON file with that information by doing the following:

import json

with open('output.json', 'w') as json_file:
  json.dump(turn_to_json, json_file)

We import the json module, open up a write-mode file under the variable json_file, and then use the json.dump() method to write to the file. json.dump() takes two arguments: first the data object, then the file object you want to save.

Instructions

In your workspace, we’ve put a dictionary called data_payload. We want to save this to a file called data.json.

Let’s start by importing the json library.

Open a new file object in the variable data_json. The filename should be 'data.json' and the file should be opened in write-mode.

Call json.dump() with data_payload and data_json to convert our data to JSON and then save it to the file data.json.
