Ever wondered what actually happens when you run a Python file?

Detailed Video: https://youtu.be/TM_dzdH1tK4

In this video, we take a behind-the-scenes look at how Python executes your code, step by step. Python doesn’t communicate with the machine directly—instead, it follows a well-defined execution pipeline.

Here’s what you’ll learn:
1. How Python source code is compiled into bytecode
2. What bytecode is and why it’s platform-independent
3. How Python stores bytecode as .pyc files inside the __pycache__ directory
4. How this process helps speed up future executions
5. The role of the Python Interpreter in executing bytecode
6. Why Python follows the principle WORA (Write Once, Run Anywhere)

How bytecode is ultimately translated into machine-level binary instructions that the CPU understands

This video is perfect for anyone who wants to understand Python internals, execution flow, and what really happens under the hood when a Python program runs.
