Mar 7, 2024 · The byte-code is loaded into the Python run-time and interpreted by a virtual machine, which is a piece of code that reads each instruction in the byte-code and executes whatever operation is indicated. Byte Code is automatically created in the same directory as .py file, when a module of python is imported for the first time, or when the ...
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.

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 ...
If you'd like to learn more about Python bytecode, the Python virtual machine, and how they work, I recommend these resources: 1. Inside the Python Virtual Machineby Obi Ike-Nwosu is a free online book that does a deep dive into the Python interpreter, explaining in detail how Python actually works. 2.

Jun 6, 2024 · 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.
Mar 5, 2020 · 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. CPython compiles the python source code into the bytecode, and this bytecode is then executed by the CPython virtual machine. Generating ...

Apr 24, 2024 · Python bytecode is a low-level, platform-independent representation of your Python code. When you run a Python script, the Python interpreter first compiles your code into bytecode before executing it. Bytecode consists of instructions that the Python virtual machine can interpret and run. Each bytecode instruction represents a specific ...
