In this article, we will study the concept and algorithm for preorder tree traversal. Then we will implement the algorithm for preorder traversal in Python and run it on a binary tree. What is Preorder Tree Traversal? Preorder traversal is a depth-first tree traversal algorithm. In depth-first traversal, we start at the root node and […]
In this article, we will learn about binary search trees. We will study the underlying concepts behind binary search trees and then implement the code. You should be familiar with the concepts of binary trees to read this article. What is a binary search tree? A binary search tree is a binary tree data structure
In this article, we will study balanced binary trees and we will try to implement a program in Python to determine if a binary tree is balanced or not. To read this article, you should be familiar with the concept of binary trees. What is a Balanced Binary Tree? A balanced binary tree is defined
Generators in Python are powerful tools to make custom iterators that can be used wherever there is a need to generate a sequence of objects. Pre-requisites We need to know two important concepts before continuing on with generators in Python. 1. Iterables An iterable is an object that returns an iterator if iter() is called
Let’s talk about a niche topic today – Decorators in Python. This is a simple but powerful tool that, as the name suggests, decorates functions. Pre-Requisite knowledge There are a few concepts we need to know before proceeding with Decorators in Python, namely, higher-order functions and nested functions – two sides of the same coin.
In this tutorial, we will learn about what binary trees are and we will study underlying concepts behind binary tree data structure. We will also implement them using classes in python. What is a Binary Tree? A Binary tree is a data structure in which there is a parent object and each object can have
In this tutorial, we will learn about what file transfer protocol is and We will implement the functionalities of file transfer protocol in Python using different methods. What is File Transfer protocol or FTP? FTP is a network protocol for file transfer between two systems in a network. It works as a client-server architecture in

A String is a sequence of characters. You are allowed to start and end a string literal with single and double quotes in Python. There are two ways to represent a string in python programming. In this article, you will see the difference between both the quotation marks with the help of an example i.e. code with

Python classmethod() is a built-in function of the Python standard library! There are three types of methods in Python: Instance Method Class Method Static Method Here, in this article, we’re going to discuss and focus on the class method of Python. So let’s get started. What is a Python classmethod()? A Python classmethod() can be
Array Indexing means searching for elements in an array using the index (position) of elements for quick retrieval of information. Getting Started with Array Indexing in Python Python arrays are variables that consist of more than one element. In order to access specific elements from an array, we use the method of array indexing. The
