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 e...

How local variables work in Python bytecode
The post explains how local variables are managed in Python bytecode: they’re stored in reserved slots at the bottom of each function’s stack frame, with the stack holding references to objects on the heap. By walking through a custom Python interpreter in Rust, the author illustrates how compiled bytecode uses indices (not names) to access these slots, demystifying the stack-based stora...
