import random

def fetch_random_url(url):
    def handle_response(response):
        if response.error:
            print("Error fetching URL:", response.error)
        else:
            print("URL response:", response.body)

    http_client = tornado.httpclient.AsyncHTTPClient()
    http_client.fetch(url, callback=handle_response)

    loop = tornado.ioloop.IOLoop.current()
