Python Interpreter Explained: How Python Code Executes Internally (2026)

Ever wondered what happens when you run a Python script? 🐍 In this video, we open up the hood of Python to understand the journey from source code to execution.

We break down the myths about interpreters vs compilers, explain what .pyc files actually are, and introduce you to the Python Virtual Machine (PVM). This is essential knowledge for any beginner wanting to master the language!

What you will learn:

1. The difference between Interpreters and Compilers
2. How Python compiles to Bytecode
3. What the Python Virtual Machine (PVM) does
4. How CPython differs from PyPy and others

Understanding these internal mechanics will help you debug errors faster and write more efficient code. 🚀
