When using
my_api = bugzilla.Bugzilla("partner-bugzilla.redhat.com")
one will get:
raise InvalidURL("Invalid URL %r: No host supplied" % url)
requests.exceptions.InvalidURL: Invalid URL 'https:///partner-bugzilla.redhat.com': No host supplied
Note the https:/// which should be https://
As workarround
my_api = bugzilla.Bugzilla("https://partner-bugzilla.redhat.com")
