  1. 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.)

Python generate theses .pyc files for a few reasons: This can make it easier to distribute Python scripts without having to worry about platform-specific issues. Bytecode in the .pyc file is not human-readable, it can provide a degree of protection for the source code.

  3. 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.

  4. Mar 20, 2022 · Files with extension .py contain Python code that is human readable. On the other side .pyc files contain bytecode that is not human readable. Files with .py extension are compiled into .pyc files that are then processed by the Python interpreter. Don’t worry if this doesn’t fully make sense, we will go through a few examples that will make ...

  5. 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.

  6. May 16, 2024 · Compiled Python Files. This is part of a series of posts examining the methods malicious Python code gains execution. This technique is more about obfuscating malicious Python code but it still demonstrates a method for that malicious code to gain execution in a non-standard way. Compiled Python modules (*.pyc files) can be imported just like ...

Understanding the differences between these two types of files is essential for efficient Python programming and debugging. '.py' files contain human-readable source code written by developers, while '.pyc' files are compiled bytecode generated by ...
