How to convert the following code to make use of urllib3 instead of urllib

    def update_email(self, device, email, backup):
        return json.loads(urlopen('%s/devices/%s/email?key=%s' % (
            self.path, device, self.key), urlencode({
                'from_email': email,
                'backup_email': backup
            })).read())
