I plan to add the Python version to the second edition of the refactoring course. This new edition will be available as a free upgrade to all existing customers. The release date is currently unknown as there is still plenty of work to be done.
Still, please note that the course is language-agnostic, and so you can apply all the gained knowledge to any OOP-focused programming language. Thus if you can read Java, C#, or PHP, you don't have to wait for the second edition.
Please let me know if you have any further questions.
When do we get an update?
