How to create a Python dictionary with double quotes as default quote format?

Question

I am trying to create a python dictionary which is to be used as a java script var inside a html file for visualization purposes. As a requisite, I am in need of creating the dictionary with all names inside double quotes instead of default single quotes which Python uses. Is there an easy and elegant way to achieve this.

    couples = [                ['jack', 'ilena'],                 ['arun', 'maya'],                 ['hari', 'aradhana'],                 ['bill', 'samantha']]     pairs = dict(couples)     print pairs 

Generated Output:

{'arun': 'maya', 'bill': 'samantha', 'jack': 'ilena', 'hari': 'aradhana'} 

Expected Output:

{"arun": "maya", "bill": "samantha", "jack": "ilena", "hari": "aradhana"} 

I know, json.dumps(pairs) does the job, but the dictionary as a whole is converted into a string which isn't what I am expecting.

P.S.: Is there an alternate way to do this with using json, since I am dealing with nested dictionaries.

Answer 1

json.dumps() is what you want here, if you use print json.dumps(pairs) you will get your expected output:

>>> pairs = {'arun': 'maya', 'bill': 'samantha', 'jack': 'ilena', 'hari': 'aradhana'} >>> print pairs {'arun': 'maya', 'bill': 'samantha', 'jack': 'ilena', 'hari': 'aradhana'} >>> import json >>> print json.dumps(pairs) {"arun": "maya", "bill": "samantha", "jack": "ilena", "hari": "aradhana"}
