How can I implement a tree data structure in Python?

You can implement a tree in Python using classes. Would you like a simple binary tree example?

Yes, please provide a simple binary tree implementation.

Here's a basic implementation:

class Node:
    def __init__(self, value):
        self.value = value
        self.left = None
        self.right = None

class BinaryTree:
    def __init__(self):
        self.root = None

    def insert(self, value):
        if not self.root:
            self.root = Node(value)
        else:
            self._insert_recursively(self.root, value)

    def _insert_recursively(self, node, value):
        if value < node.value:
            if node.left is None:
                node.left = Node(value)
            else:
                self._insert_recursively(node.left, value)
        else:
            if node.right is None:
                node.right = Node(value)
            else:
                self._insert_recursively(node.right, value)

How do I traverse this tree?

You can traverse the tree using in-order, pre-order, or post-order methods. Would you like to see examples of these?
