Python Bytecode: A Beginner’s Guide

Python bytecode is like a secret language that Python uses behind the scenes. When you write your Python code, it doesn’t run directly. Instead, Python translates your code into bytecode, a set of instructions that the Python interpreter can understand and execute.
You may be asking why beginners should care about bytecode. Well, understanding bytecode helps you peek under the hood of Python and see how your code works. This knowledge can help you write better, more efficient programs. Even if you don’t see bytecode directly, it’s a crucial part of making Python run smoothly.
In this guide, we’ll unravel the mystery of Python bytecode and show you why it matters.
What is Python Bytecode?
Python bytecode is like a middleman between your Python code and your computer’s hardware. When you write Python code and run it, the interpreter first translates your code into bytecode.
This bytecode is a lower-level representation of your code, but it’s still not something that your computer’s processor can understand directly.
That’s where the Python Virtual Machine (PVM) comes in. The PVM is like a special engine that’s designed to run bytecode. It reads the bytecode instructions one by one and carries them out, making your Python program come to life.
