Python Tutorial: Type Hinting vs Type Checking vs Data Validation – What’s the Difference?

In this video, we’ll be learning about the differences between type hinting, type checking, and data validation in Python. These are three concepts that many developers get confused about, so we’ll cover what each one does, when to use them, and how they work together. We’ll also look at practical examples using tools like mypy for type checking and Pydantic for data validation. By the end of this video, you’ll have a clear understanding of these important Python concepts and know when to apply each one in your own projects. Let’s get started…
