   stackoverflow.com › questions › 471191

   Beginners assume Python is compiled because of .pyc files. The .pyc file is the compiled bytecode, which is then interpreted. So if you've run your Python code before and have the .pyc file handy, it will run faster the second time, as it doesn't have to re-compile the bytecode.

   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.

   Apr 23, 2018 · This intermediate format is called "bytecode." So those .pyc files Python leaves lying around aren't just some "faster" or "optimized" version of your source code; they're the bytecode instructions that will be executed by Python's virtual machine as your program runs. Let's look at an example.

   When a Python script is run, CPython loads the bytecode from the .pyc files (if available) or compiles the source code into bytecode if necessary. The virtual machine then executes the bytecode instructions one by one, pushing and popping values on a stack as needed to perform operations. Bytecode Files (.pyc)

   What is Python bytecode?

   • .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. .pyd : A windows DLL file for python.

   What do the python file extensions, .pyc .pyd .pyo stand for?

   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:

   Why should you learn Python bytecode?

   • Understanding Python’s bytecode allows you to get familiar with the low-level implementation of the Python compiler and virtual machine. If you know how your source code is converted to the bytecode, you can make better decisions about writing and optimizing your code.

   Where is Python bytecode stored?

   • CPython compiles the python source code into the bytecode, and this bytecode is then executed by the CPython virtual machine. In Python, the bytecode is stored in a .pyc file. In Python 3, the bytecode files are stored in a folder named __pycache__.
