How can I implement a binary tree in Python?

To implement a binary tree in Python, you can create a class for the tree nodes. Each node will have a value and pointers to left and right children.

Can you show me a simple code example?

Sure! 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

How do I add elements to the binary tree?

You can create an insert method in the BinaryTree class to add elements. Would you like to see that?

Yes, please!

Here's how you can implement the insert method:

def insert(self, value):
    if self.root is None:
        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)
