Because that's how the true value is spelt in JavaScript. You _are_ 
aware that JSON is "JavaScript Object Notation", are you not? So 
json.dumps translates Python values into JavaScript syntax.

This is likely to be the same reason you were wondering about None vs 
null; broadly, the Python None value serves the same purpose as the 
JavaScript null value, and therefore that is how it is expressed in 
JSON.
