- The reason some files get compiled automatically is because they are imported; for instance, if you use import mylib.py, Python will compile mylib.py so that future import statements run a little faster. If you later change mylib.py, then it will get re-compiled next time it is imported (Python uses the file date to see that this happens.)

May 30, 2024 · The Python interpreter generates .pyc files automatically when a .py file is imported or executed. When a Python script is executed, the interpreter first checks if there is a corresponding .pyc file for that script.
There are several methods to compile Python code. To create executable files, you can use tools like PyInstaller, cx_Freeze, or py2exe. Additionally, you can compile Python modules using the built-in compile() function.
Jul 1, 2024 · Here’s what happens behind the scenes: 1. Compilation to Bytecode: Hidden Compilation: The Python interpreter first translates your source code into an intermediate form known as bytecode. This step is automatic and hidden from you, the programmer. You don’t need to run a separate command for this; it happens when you execute your script.
May 16, 2024 · Compiled Python modules can only run on matching interpreter versions. The solution is to create multiple built distributions, one for each of the targeted Python versions, with matching compiled modules.
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 language.

Feb 26, 2012 · 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.
