Python program to insert an element in binary tree.



Description:

To add an element into a binary tree we just need to write the insert function compares the value of the node to the parent node and decides to add it as a left node or a right node. Finally the "PrintTree" method  is used to print the tree.

Program:

class Node: def __init__(self, data): self.left = None self.right = None self.data = data def insert(self, data): if self.data: if data < self.data: if self.left is None: self.left = Node(data) else: self.left.insert(data) elif data > self.data: if self.right is None: self.right = Node(data) else: self.right.insert(data) else: self.data = data # To Print the tree def PrintTree(self): if self.left: self.left.PrintTree() print( self.data), if self.right: self.right.PrintTree() # Use the insert method to add nodes root = Node(12) root.insert(6) root.insert(14) root.insert(3) root.PrintTree()


Output:
3
6
12
