Python is often described as an interpreted language—one in which your source code is translated into native CPU instructions as the program runs—but this is only partially correct. Python, like many interpreted languages, actually compiles source code to a set of instructions for a virtual machine, and the Python interpreter is an implementation o...
CPython uses a stack-based virtual machine. That is, it's oriented entirely around stack data structures (where you can "push" an item onto the "top" of the structure, or "pop" an item off the "top"). CPython uses three types of stacks: 1. The call stack. This is the main structure of a running Python program. It has one item—a "frame"—for each cur...
If you want to play around with this, the dis module in the Python standard library is a huge help; the dis module provides a "disassembler" for Python bytecode, making it easy to get a human-readable version and look up the various bytecode instructions. The documentation for the dis modulegoes over its contents and provides a full list of bytecod...
Now that you've read this far, you might be thinking "OK, I guess that's cool, but what's the practical value of knowing this?" Setting aside curiosity for curiosity's sake, understanding Python bytecode is useful in a few ways. First, understanding Python's execution model helps you reason about your code. People like to joke about C being a kind ...

Jun 6, 2024 · Python bytecode is the hidden language that makes your Python program run. It’s a lower-level representation of your code that the Python interpreter understands and executes. Bytecode is generated from your source code through a compilation process and stored in .pyc files for faster execution in future runs.
May 10, 2020 · Bytecode is an intermediate language for the Python virtual machine that’s used as a performance optimization. Instead of directly executing the human-readable source code, compact numeric codes, constants, and references are used that represent the result of compiler parsing and semantic analysis.
