fbdisconnect is not working

fbdisconnect function not working.

Is my understanding that some code is missing, see below:
Githbub Link:
https://github.com/udacity/ud330/blob/master/Lesson4/step2/project.py

Code:

@app.route('/fbdisconnect')
def fbdisconnect():
    facebook_id = login_session['facebook_id']
    # The access token must me included to successfully logout
    access_token = login_session['access_token']
    url = 'https://graph.facebook.com/%s/permissions?access_token=%s' % (facebook_id,access_token)
    h = httplib2.Http()
    result = h.request(url, 'DELETE')[1]
    return "you have been logged out"

Correct code that worked for me:

@app.route('/fbdisconnect')
def fbdisconnect():
    facebook_id = login_session['facebook_id']
    # The access token must me included to successfully logout
    access_token = login_session['access_token']
    url = 'https://graph.facebook.com/%s/permissions?access_token=%s' % (facebook_id,access_token)
    h = httplib2.Http()
    result = h.request(url, 'DELETE')[1]
    del login_session['username']
    del login_session['email']
    del login_session['picture']
    del login_session['user_id']
    del login_session['facebook_id']
    return "you have been logged out"
