Apr 23, 2018 · I'll take you through what Python bytecode is, how Python uses it to execute your code, and how knowing about it can help you. How Python works. 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.
Jul 10, 2020 · The byte code instructions are created in the .pyc file. The .pyc file is not explicitly created as Python handles it internally but it can be viewed with the following command: -m and py_compile represent module and module name respectively. This module is responsible to generate .pyc file.
Feb 25, 2024 · What Exactly is Python Bytecode? 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.
Jun 6, 2024 · You can use the dis module to view and analyze bytecode, gaining insights into how Python translates your code into instructions. By understanding common bytecode instructions and their role in basic Python constructs like loops and conditionals, you can optimize your code for better performance.
Nov 23, 2013 · Bytecode is a generic word for the instructions executed by a virtual machine, in the same way that machine language is a generic term for the instructions executed by a real processor. Just as there are many different machine instruction sets, there are many different bytecode instruction sets.
Mar 5, 2020 · In Python 3, the bytecode files are stored in a folder named __pycache__. This folder is automatically created when you try to import another file that you created: import file_name. However, it will not be created if we don’t import another file in the source code. In that case, we can still manually create it.

Why is bytecode better than Python?
Python scripts are being compiled on execution to Python's bytecode language, and the compiled files (.pyc) are cached inside the script's folder; Compiled code can be analysed and investigated using a built-in tool for debugging the low-level bytecode. The tool can be initialized from the shell, for example:
