Escape double quotes for JSON in Python

Note that you can escape a json array / dictionary by doing json.dumps twice and json.loads twice:

>>> a = {'x':1}
>>> b = json.dumps(json.dumps(a))
>>> b
'"{\\"x\\": 1}"'
>>> json.loads(json.loads(b))
{u'x': 1}

You should be using the json module. json.dumps(string). It can also serialize other python data types.

import json

>>> s = 'my string with "double quotes" blablabla'

>>> json.dumps(s)
<<< '"my string with \\"double quotes\\" blablabla"'
