python - How to parse data in JSON format?

Question

My project is currently receiving a JSON message in python which I need to get bits of information out of. For the purposes of this, let's set it to some simple JSON in a string:

jsonStr = '{"one" : "1", "two" : "2", "three" : "3"}'

So far I've been generating JSON requests using a list and then json.dumps, but to do the opposite of this I think I need to use json.loads. However I haven't had much luck with it. Could anyone provide me a snippet that would return "2" with the input of "two" in the above example?

Very simple:

import json
data = json.loads('{"one" : "1", "two" : "2", "three" : "3"}')
print data['two']  # Or `print(data['two'])` in Python 3
