I don't know how to solve ReCAPTCHA

I have taken the unCaptcha module from Kodi 18 and converted it to Python 3. I have run a little code but right in the last step the server responds that I have JavaScript disabled, which means that I am stuck here. I am trying to make it work from the XML that calls the unCaptcha module, please help me?
