Using dict with JSON

JSON natively supports a mapping-type object, which is equivalent to a Python dictionary. This means that we can work directly with dict through JSON. In this example, we import the json package and we display the contents of the dictionary-type object called books in JSON format:

>>> import json>>> books = {'A':'Book1', 'B':'Book2', 'C':'Book3'}>>> type(books)<class 'dict'>>>> books['A']'Book1'>>> books['B']'Book2'>>> books['C']'Book3'>>> books['D']Traceback (most recent call last): File "<stdin>", line 1, in <module>KeyError: 'D'>>> json.dumps(books)'{"A": "Book1", "B": "Book2", "C": "Book3"}'Now the text string resulting from the conversion will be linked to the name books_json.>>> books_json = json.dumps(books)>>> ...
