Get json object without JSON.parse?

Programmer Question

I found this:

Use Python output:

print �Content-type: text/x-json\n\n�
print json.dumps([{'title':arr['title']}])

and get json string with Jquery:

$ajax(   
   success: function(msg){
      if(msg[0].title) alert(msg[0].title);
   }
)

It works, who can tell me why it is? Thanks~
