When Python executes a program, Python reads the .py into memory, and parses it in order to get a bytecode, then goes on to execute. For each module that is imported by the program, Python first checks to see whether there is a precompiled bytecode version, in a .pyo or .pyc, that has a timestamp which corresponds to its .py file.
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 ...
Aug 10, 2023 · The Python source code goes through the following to generate an executable code. Step 1: The Python compiler reads a Python source code or instruction in the code editor. In this first stage, the execution of the code starts. Step 2: After writing Python code it is then saved as a .py file in our system.

Nov 16, 2015 · The syntax is as follows: import py_compile. py_compile.compile("file.py") This method of compiling will not execute the module either like running python file.py. There is also a method that compiles an entire directory tree but I'll let you check out the link to see how that is executed. Hope this helps.
