title: Python parsing JSON with escaped double quotes
body: <p>Consider this valid json:</p>
  
  <p><code>{"a": 1, "b": "{\"c\":2}"}</code></p>
  
  <p>Python's <code>json</code> module throws when I try to parse it - it looks like the <code>\"</code> is throwing it off:</p>
  
  <pre>
  json.loads('{"a": 1, "b": "{\"c\":2}"}')
  Traceback (most recent call last):
    File "", line 1, in 
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
      return _default_decoder.decode(s)
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 365, in decode
      obj, end = self.raw_decode(s, idx=_w(s, 0).end())
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 381, in raw_decode
      obj, end = self.scan_once(s, idx)
  ValueError: Expecting , delimiter: line 1 column 15 (char 14)
  </pre>
  
  <p>Is there any way to parse this in Python, either using the <code>json</code> module or some other module like <code>ujson</code>?</p>
