Converting dictionary to JSON

Question

r = {'is_claimed': 'True', 'rating': 3.5} r = json.dumps(r) file.write(str(r['rating'])) 

I am not able to access my data in the JSON. What am I doing wrong?

TypeError: string indices must be integers, not str 

Answer 1

json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method

See json.dumps() as a save method and json.loads() as a retrieve method.

This is the code sample which might help you understand it more:

import json  r = {'is_claimed': 'True', 'rating': 3.5} r = json.dumps(r) loaded_r = json.loads(r) loaded_r['rating'] #Output 3.5 type(r) #Output str type(loaded_r) #Output dict 

Answer 2

json.dumps() returns the JSON string representation of the python dict. See the docs

You can't do r['rating'] because r is a string, not a dict anymore

Perhaps you meant something like

r = {'is_claimed': 'True', 'rating': 3.5} json = json.dumps(r) # note i gave it a different name file.write(str(r['rating']))
