FYI: requests is so much more elegant code same as yours looks similar,
but there's a lot more to offer, see: https://requests.readthedocs.io/en/master/

needs to be installed once, pip install requests (request with an s = requests)

simple example:

import requests
url='http://python.org/'
response = requests.get(https://qrznow.com/real-time-band-conditions/)
print(response.content)
