Is Python interpreted, or compiled, or both?
What happens when you run a Python program — is it interpreted directly, compiled first, or a mix of both? Let’s explore how Python handles code execution and what makes it unique compared to other languages!
Python is both interpreted and compiled — but not in the way you might expect! When you run a Python script, it first gets compiled into bytecode, and then that bytecode is interpreted by the Python Virtual Machine (PVM).
Here's a simple breakdown:
Compilation step:
Python automatically compiles your .py file into a .pyc (bytecode) file behind the scenes. You usually don’t notice this happening!
Interpretation step:
The Python Virtual Machine (PVM) reads this bytecode and executes it line-by-line.
Not like traditional compiled languages:
Unlike C or Java, Python doesn't compile directly into machine code or run a separate compilation step you must manually do.
Why it matters:
This process makes Python flexible and easy to debug, but also a little slower compared to purely compiled languages.
In short, Python is often called an interpreted language, but technically it goes through a "compile and interpret" process. You usually don't worry about it — you just run your script, and Python handles the rest!
Quick tip: If you see .pyc files in your project folders, that’s the compiled bytecode!
