Python source code is automatically compiled into Python byte code by the CPython interpreter. Compiled code is usually stored in PYC (or PYO) files, and is regenerated when the source is updated, or when otherwise necessary. To distribute a program to people who already have Python installed, you can ship either the PY files or the PYC files.
Feb 26, 2012 · 73. Python has a compiler! You just don't notice it because it runs automatically. You can tell it's there, though: look at the .pyc (or .pyo if you have the optimizer turned on) files that are generated for modules that you import. Also, it does not compile to the native machine's code.
The “py_compile” module can be used to compile individual Python files. To compile a Python file using the “py_compile” module, import the module and use the “compile” function: import py_compile. py_compile. compile (‘filename.py’) The compiled bytecode will be saved in a file with a “.pyc” extension.
Jul 11, 2015 · 11. I can understand the fact that Java needs both a compiler and an interpreter. It compiles source code to bytecode and then a virtual machine (on Windows, on Linux, on Android, etc.) translates that bytecode to machine code for the current architecture. But why does Python need both a compiler and an interpreter?
Oct 10, 2022 · The short answer is: Python is interpreted. There is no separate compile step after writing Python code and before running the .py file. The Python interpreter software you download from python.org is called CPython because it's written in C. Python can be compiled into a binary executable with a tool like Py2Exe (on Windows), py2app (on macOS ...
You never invoke a compiler, you simply run a .py file. The Python implementation compiles the files as needed. This is different than Java, for example, where you have to run the Java compiler to turn Java source code into compiled class files. For this reason, Java is often called a compiled language, while Python is called an interpreted ...

A lot of processes happen between pressing the run button on our IDEs and getting the output, and half of that process involves the working of compilers. 1. When we run a Python file (.py), the compiler starts reading the file. 2. The compiler reads the file and checks for errors. 3.
