Understanding Python's Internal Working: A Beginner's Dive 🐍

Python is widely loved for its simplicity, but understanding its internal workings can elevate your programming skills to the next level. If you’ve ever wondered how Python works under the hood, you’re in for an exciting journey. In this blog, I’ll break down the basics of Python’s internal mechanics and share a great YouTube playlist to guide you through the process.

What Happens When You Run Python Code?

When you execute Python code, the following steps occur:

1. Compilation to Bytecode

   • Your Python code (.py file) is compiled into bytecode (.pyc file). Bytecode is a lower-level representation of your code that the Python interpreter can execute.

2. Execution by the Python Virtual Machine (PVM)

   • The bytecode is executed by the PVM, which translates it into machine code that your system can run.

3. Garbage Collection

   • Python manages memory automatically using a garbage collector, which removes objects no longer in use to free up memory.

Key Components of Python's Architecture

1. Interpreter
   Python uses an interpreter (CPython is the most popular) to process your code.

2. Global Interpreter Lock (GIL)
   A unique feature of CPython, the GIL ensures only one thread runs Python bytecode at a time. This simplifies memory management but limits multi-threading performance.

3. Modules and Libraries
   Python's extensive standard library enhances its functionality without the need for external tools.
