How about not using type hints when teaching the basics of trees?

Type hints do not replace good variables names. What about using 
left_tree instead of left and right_tree instead of right?
That should simplify the example for the students, remove advanced 
concepts and teach them something about right naming (conventions) which 
is desirable these days when looking at production code (readability, 
maintainability and so forth).
