Python programing language is an interpreter language which converts the python code to the bytecode. These bytecodes are created by a compiler present inside the interpreter. Interpreter first compiles the python code t0 the byte code which is also called as the intermediate code, then the code is used to run on the virtual machine.

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.
Feb 25, 2024 · Bytecode is the under-the-hood representation of your Python code, a middle-ground between the high-level Python you write and the binary machine code executed by the computer’s processor. When you run a Python script, your code is transformed into this low-level, platform-independent format, which the Python Virtual Machine (PVM) then executes.

Mar 5, 2020 · After compilation, the bytecode is sent for execution to the PVM. The PVM is an interpreter that runs the bytecode and is part of the Python system. The bytecode is platform-independent, but PVM is specific to the target machine. The default implementation of the Python programming language is CPython which is written in the C programming language.
