title: python json boolean to lowercase string
body: <p>Is there a best-practice for outputting Booleans in Python? I'm generating some JSON (via Django templates), and by default all the Boolean values are output with leading character in uppercase, contrary to the JSON standard (ie, "True" as opposed to "true").</p>
  
  <p>Currently, I format each Boolean string using str.lower(), but is there a better way?</p>
