Output from HTTPConnection debug level when using python's http.client

I'm trying to get debug information from python's built in httpclient. In a console I tried

from http.client import HTTPSConnection
HTTPSConnection.debuglevel = 1

a_url = 'https://feeds.simplecast.com/wgl4xEgL'
from urllib.request import urlopen
response = urlopen(a_url)

I expected to see some debug output either to stdout or stderr but don't see any output. I tried using the HTTPSConnection.set_debuglevel method too. How can I see the debug output?

EDIT : Realized I was using HTTPConnection I tried HTTPSConnection and updated that snippet above to reflect that.
