ValueError when converting a string to dict:dictionary update sequence element #0 has length 1; 2 is required

Question

I'm trying to convert a string to a dictionary but I keep getting this error:
ValueError: dictionary update sequence element #0 has length 1; 2 is required
Here's my code:

string = r'{"extra":[{"text":"Hello World"}]}'
json_data = dict(string)

You can't just load a JSON text just like that. You need the json parser: docs.python.org/3/library/json.html (particularly the loads function to decode the string into a Python dict) — Savir

I believe you are looking for:

import json
string = r'{"extra":[{"text":"Hello World"}]}'
json_data = json.loads(string)

There are a few JSON parsing libraries. Default one should suffice, simplejson is another option (just to give you an alternative).
