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

Sometimes your json is not a string  For example if you are getting a json from a url like this   j   urllib2 urlopen  http   site com data json     you will need to use json load  not json loads   j obj   json load j     it is easy to forget  the  s  is for  string
