My Question or Issue

I am calling using the v1/me/player/play endpoint. I am getting Response 400 Malformed json. I had followed this 
This is my code: 

import requests

headers = {

    'Content-Type': 'application/json',

    'Authorization': 'Bearer {}'.format(s.token)

}

json_data = {

    'uris': 'spotify:track:6habFhsOp2NvshLv26DqMb'

}

url =  'https://api.spotify.com/v1/me/player/play?' + device_id

response = requests.put(url, headers=headers, json=json_data)

uris is an array. has to be 'uris' : ['track']
