Python Programs on Trees

Python Programming Examples - Trees

A tree is a data structure that uses references to connect data elements in a hierarchical form. Every tree has a root node from which we can access all the elements of the tree. The tree structure consists of root nodes, leaf nodes, and internal nodes. Each node has a reference to one of its children, which is known as an edge. Trees are often used for efficient data storage and fast browsing and indexing when searching for data.

The following section contains Python programs on trees, binary trees, binary search trees, binomial tree, nodes of a tree, tree traversals, BFS, and DFS tree traversals. Each sample program includes a program description, Python code, and program output. All examples have been compiled and tested on Windows and Linux systems.
