How do I implement a binary tree in Python?

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

Can you show me a simple example of a binary tree class?

Sure! Here's a basic implementation:

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

How do I add nodes to this binary tree?

You can create a method to insert nodes. For example, you can insert nodes based on their value, placing smaller values to the left and larger values to the right.

Can you provide the insert method code?

Absolutely! Here's a simple insert method:

def insert(self, value):
    if value < self.value:
        if self.left is None:
            self.left = TreeNode(value)
        else:
            self.left.insert(value)
    else:
        if self.right is None:
            self.right = TreeNode(value)
        else:
            self.right.insert(value)
