Connecting to an API in Python

import requests url = 'http://www.omdbapi.com/?t=hackers' r = requests.get(url) json_data = r.json() for key, value in json_data.items(): print(key + ':', value)

What was that URL?

hp - making an HTTP request www.omdbapi.com - querying the OMDB API

?t=hackers

Query string Return data for a movie with title (t) ‘Hackers’

'http://www.omdbapi.com/?t=hackers'
