When you start learning Python, one of the first things you’ll come across is data types. Think of them as the different kinds of values your code can work with. Just like you wouldn’t use a calculator to store text messages, Python needs to know what type of data it’s handling to treat it correctly.
In this guide, we’ll walk through the most important data types in Python with simple examples.

Linked lists are one of the fundamental data structures in computer science. A common interview question (and practical exercise) is how to take the last node of a singly linked list and move it to the front.
Let’s walk through the logic, example code, and why this operation matters.

When learning Ruby, understanding its built-in data types is one of the most important steps. Data types define the kind of values you’re working with and how Ruby interprets and manipulates them.
Ruby keeps things simple but powerful — everything is an object, and each data type comes with its own methods and behaviors.
Let’s walk through Ruby’s essential data types with examples you can try right away.
