## python tree

## Introduction

In computer science, a

**tree**is a

**data**

**structure**that is modeled after nature. Unlike trees in nature, the tree data structure is upside down: the root of the tree is on top. A tree consists of nodes and its connections are called edges. The bottom nodes are also named leaf nodes. A tree may not have a cycle.

A tree with eight nodes. The root of the tree (5) is on top.

Python does not have built-in support for trees.

## Binary tree

**A binary**

**tree**is a data structure where every node has at most two children (left and right child). The

**root**of a tree is on top. Every node below has a node above known as the parent node.We define a class thee which has a left and right attribute. From this binary tree we define the root (top of the three) and a left and right node.
