   Jan 11, 2012 · When -O is used, all bytecode is optimized; .pyc files are ignored and .py files are compiled to optimized bytecode. Passing two -O flags to the Python interpreter (-OO) will cause the bytecode compiler to perform optimizations that could in some rare cases result in malfunctioning programs.

   Mar 20, 2022 · Files with .py extension are Python source files, the files in which you write your Python code. The Python code you write in .py files is not executed in the same format by the machine on which you run your code. Before being executed, the code in the .py files is compiled into .pyc files.

   When you run a Python program, the interpreter translates the code into bytecode, which is a lower-level representation of the code that can be executed by the Python virtual machine. By default, the bytecode is stored in .pyc files, which are created in the same directory as the corresponding .py file.

   What is a Python bytecode file?

   • The .pyc extension refers to Python bytecode files. When a .py file is executed, the Python interpreter compiles the file into a format known as bytecode to speed up the start-up time of the script in future runs. This compiled version is stored with a .pyc extension. In Python3, these .pyc files are stored in a subfolder named __pycache__.

   How does Python execute bytecode?

   • Compilation to Bytecode: Python’s compiler translates the source code (.py files) into bytecode (.pyc files). Bytecode Interpretation: The PVM reads and executes the bytecode. Python’s execution model differs from both compiled and interpreted languages:

   Why is Python compiled to bytecode?

   • It's compiled to bytecode which can be used much, much, much faster. The reason some files aren't compiled is that the main script, which you invoke with python main.py is recompiled every time you run the script. All imported scripts will be compiled and stored on the disk. Important addition by Ben Blank:

   Is CPython a bytecode?

   • The answer is: it depends on the Python implementation you are using. The reference implementation of Python is called CPython and it’s written in C and Python. In this implementation Python code is compiled into bytecode by a compiler before being interpreted. How can you confirm if you are using CPython?

   What are Python files?

   • This answer should discuss .pth files. .py : The input source code that you have written. .pyc : The compiled bytecode. If you import a module, python will build a .pyc a file that contains the bytecode to make importing it again later easier (and faster). .pyo : A .pyc file that was created while optimizations (-O) were on.

   Mar 5, 2020 · When we execute a source code (a file with a .py extension), Python first compiles it into a bytecode. The bytecode is a low-level platform-independent representation of your source code, however, it is not the binary machine code and cannot be run by the target machine directly.
