[GH Python] No callable method error while using DataTree class

Some methods of the DataTree class seem to be uncallable. I have found this error while using RenumberPaths() and Flatten. Maybe I’m using the wrong syntax?

I partially undertand that this class is born for C#. Maybe that’s why some methods are incompatible with other languages?

Let me know if there IS a way to use these methods in Python, and what the right way would be! Thank you!
