How to Implement a Stack from Scratch in Python

There’s no other data structure like the Stack. In only a few minutes, you can have a fully working implementation that can be used to solve a wide variety of problems. Stacks are useful for anything from reversing a string to language processing applications – not to mention the fact that many programming languages (and probably your operating system) rely on a Stack to function.

How to Implement a Custom Linked List in Python

Need a quick run down on a classic data structure? Look no further.

Click here for the full LinkedList source code. Also, here is the test code.

A linked list is an ordered collection of elements. The thing that makes it special is how it stores data. Behind the scenes, each number, string, object, or other value you may need to keep track of is stored in a Node. Each Node references its successor.

How to Implement a Queue From Scratch Using Python

You may hate the line at the DMV, but without it, things might turn into a rough-and-tumble free for all! In the same way that a line keeps raging motorists from getting out of hand, a Queue helps your computer keep its ducks in a row. The Queue functions very much like a line of people. It’s a First-In, First-Out (FIFO) data structure, so no cutting!

How to Implement a Custom Hash Table in Python

This tutorial will show you how to implement a hash table with separate chaining. It’s not the most efficient method, but it is the simplest way to get started and create a fully functioning hash table.

How to Implement a Binary Search Tree in Python

Decisions, decisions… Life is all about choices! Usually there are so many ways to go. An infinite expanse of roads and pathways stretches in front of you, an endless gradient of details; as you consider them, your head starts to spin, your eyes start to droop, your mind races, your head pounds –

Wait a second. There’s no need to stress. Since we’re talking about Binary Search Trees, decisions are going to be a lot easier. A Binary Search Tree (BST) gives you two choices: left or right, less than or greater than, 0 or 1 – hence the name, binary.

How to Implement Quicksort – Essential Sorting Algorithms in Python

In this video, we learn the ins and outs of Quicksort, a sorting algorithm that will come in handy in many situations. We go over theory, and then visualize the entire sorting process from start to finish.

We cover the quicksort method in general, as well as two partition schemes: Lomuto and Hoare methods. Lomuto is simpler, but the Hoare method, named for Quicksort’s inventor, C.A.R. Hoare, is more efficient. \
