In this article, we’ll calculate the Weighted Moving Average in Python. Weight Moving Average or WMA is used extensively in trading setups Understanding Moving Averages A Moving Average is used to analyze the time-series data by calculating averages of different subsets of the complete dataset. Moving Average is also known as Rolling or Running Average. […]

In this article, we will learn about the level order binary tree traversal. First We will look at the underlying concepts behind level order traversal and then we will implement level order traversal for binary trees in python. What is Level Order Traversal? Level order traversal is a breadth-first binary tree traversal technique. We first
In this article, we will study the concept and algorithm for postorder tree traversal. Then we will implement the algorithm for postorder traversal in python and run it on a binary tree. What is Postorder Tree Traversal? Postorder traversal is a depth-first tree traversal algorithm. In depth-first traversal, we start at the root node and
In this article, we will study the concept and algorithm for inorder tree traversal. Then we will implement the algorithm for inorder traversal in python and run it on a binary search tree. What is Inorder Tree Traversal? Inorder Traversal is a depth first tree traversal algorithm. In depth first traversal, we start at the

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
