I really hope the original author, schurpf, replies. With a few very minor tweaks I was able to get a demo of pyhk working with Python 3. I have uploaded the modified file to my own repository but will be more than happy for you to use it! I apologize in advance for being new to GitHub; I should have forked this project or something but I was just too excited to add this functionality to a Selenium driver.
