rest - Using python 'requests' to send JSON boolean -

i've got simple question, can't figure out how it. problem have want send following payload using python , requests:

{ 'on': true }

doing this:

payload = { 'on':true } r = requests.put("http://192.168.2.196/api/newdeveloper/lights/1/state", data = payload)

doesn't work, because following error:

nameerror: name 'true' not defined

sending true 'true' not accepted server, that's not option. suggestion? thanks!

you need json encode string.

import json  payload = json.dumps({"on":true})
