The program does not work, what address should I use?

Question

YouTube

Guys, hello! There is the following code:

import json
from urllib.request import urlopen
url = "https://gdata.youtube.com/feeds/api/standardfeeds/top_rated?alt=json"
response = urlopen(url)
contents = responce.read()
text = contents.decode ('utf8')
data = json.loads(text)
for video in data['feed']['entry'][0:6]:
    print(video['title']['$t'])

The fact is that it does not work, as I understand it, the url address is not relevant, tell me how to fix the situation ?!
