Stack (Implementation)
Explore the process of implementing a stack data structure from scratch in Python using lists. Learn to create stack operations like push, pop, peek, is_empty, and size with constant time efficiency. Understand core stack concepts by coding your own class for practical mastery.
We'll cover the following...
Introduction
Most programming languages come with the built-in Stack data structure. In Python, you can use the pre-built Stack class by importing them into your program. However, implementing a Stack from scratch will allow you to truly master the ins and outs of the data structure.
Implementation
Stacks can be implemented using Lists or Linked Lists in Python language. Each implementation has its own advantages and disadvantages. Here, however, we will show an implementation of stacks using lists.
A typical Stack must contain the following functions:
