  1. Jun 6, 2024 · Compilation: When you run your program, the Python interpreter gets to work. It reads your source code and translates it into bytecode, a lower-level representation of your code that’s more efficient for the computer to handle. This bytecode gets saved in a separate file with a .pyc extension (e.g., my_program.pyc).

  2. Mar 7, 2024 · Whenever the Python script compiles, it automatically generates a compiled code called as byte code. The byte-code is not actually interpreted to machine code, unless there is some exotic implementation such as PyPy.

  3. Jul 22, 2024 · By compiling source code into bytecode, Python achieves several key advantages: Platform Independence: Bytecode is designed to be platform-independent, meaning it can run on any system that...

  4. Jun 8, 2023 · Compilation: Your Python source code goes through a compilation process when you run or execute it. The Python compiler, which is a component of the CPython interpreter, converts your source...

    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.

  5. Aug 16, 2023 · Python inherently compiles code to bytecode internally, so the understanding of this concept isn’t built into the language’s syntax. To interact with Python bytecode directly, we will be using Python’s built-in dis module. The dis module provides the means to analyze Python bytecode by “disassembling” it into a human-readable form.
