Ok, this video is two years old, and you've moved on to a lot of other things. But I just want to point out - because I've searched - while there are plenty of so-called tutorials about binary trees, there is almost nothing about general trees. I get it, people always want to take the easiest option, even if that doesn't really help their followers in the long run - or the short run, for that matter, because they quickly find out that too simplistic tutorials don't get you very far in the real world. So this is an appreciation, and a thank you, for the thoroughness and completeness of your work, and your interest in actually helping people learn what they need to know.

sir , I had my computer teachers in my college . But you are the one who actually taught me the Data Structure concepts and made me think why they were important and why we need to do know it . Some teachers sometimes dont know , how critical their roles are in some one life . Happy Teachers day to you even though today is not the teacher's day

I often find that writing iteration-over functions in the same space as recursion-into functions can cause people a ton of issues with understanding. Instead, you could also write get_level() recursively like this: def get_level(): if not self.parent: return 0 else: return self.parent.get_level() + 1

I got a small doubt. print_tree is a method of class (Treenode) right. at the end of the code, we used (print_tree) method. Rather than using (root.Treenode._print_tree) why we are using just(root._print_tree)

Parent was inititialized to None in the beginning because the root doesn’t have a parent but in the add_child() function, since this function adds children to the list using self.children.append(child) it becomes a parent hence child.parent=self I’m not good at teaching hope you this makes sense lol

There are no problems in doing that stackoverflow.com/questions/444296/how-to-efficiently-build-a-tree-from-a-flat-structure You just need to have 1 loop, on each step you check, if element has a parentId, if true then get the parent from the original array then do parentNode.children.add(elementNode); elementNode.parent = parentNode; (I have omitted parent/element node creation)

You can set nodes dynamically. When you do that you need to balance out a tree by re arranging nodes
