Are PYC files portable?

Are PYC files portable?

It should be portable across platforms for the same version. There is not a common reason for you to use it; Python uses it to optimize out parsing of your . py file on repeated imports. Your life will be fine ignoring the existence of pyc files.

Can Python run .PYC files?

pyc file is not compiled in the strictest sense of the term, as it is not native machine code. It is, as @tomdachi wrote, python-specific byte-code (very similar to a Java . class), that’s why it still needs the python interpreter to execture. in fact, the pyc only was generated when you import the py file.

Should I push PYC files?

These files are compiled versions of the code already in the repo, so that Python can execute the code faster. Since they are a direct computational result of the actual source code there’s no benefit to checking them in – they’d just need to be updated every time the source code was updated.

What is the difference between .py and .PYC files?

. py files contain the source code of a program. Whereas, . pyc file contains the bytecode of your program.

Is PYC faster than py?

A program doesn’t run any faster when it is read from a “. pyc” or “. pyo” file than when it is read from a “. py” file; the only thing that’s faster about “.

How can I protect my Python code but still make it available to run?

Use Cython, Nuitka, Shed Skin or something similar to compile python to C code, then distribute your app as python binary libraries (pyd) instead. That way, no Python (byte) code is left and you’ve done any reasonable amount of obscurification anyone (i.e. your employer) could expect from regular Code, I think.

How do I decode a PYC file?

How to decompile compiled . pyc Python files

  1. Install uncompyle6. pip install uncompyle6.
  2. Run uncompyle6 from Windows command prompt. Make sure you have added your Python directory to Path in your environment variables.
  3. Decompile . pyc file in your local directory.

How do you avoid Pycache?

Eliminate Python __pycache__ directories For Windows, set environment variable PYTHONDONTWRITEBYTECODE to 1 . For MacOS / Linux in ~/. profile, ~/. zprofile or other appropriate shell configuration file add the line export PYTHONDONTWRITEBYTECODE=1 .

Should you push __ Pycache __?

__pycache__ is among the directories that shouldn’t be pushed to remote repositories. Therefore, all you need to do is specify the directory in . gitignore file. Note that for Python projects in general, there are a lot more files that need to go into .

What are .PYC files used for?

pyc file contains the “compiled bytecode” of the imported module/program so that the “translation” from source code to bytecode can be skipped on subsequent imports of the *. py file. Having a *. pyc file saves the compilation time of converting the python source code to byte code, every time the file is imported.

Why .PYC file is created?

pyc files are created by the Python interpreter when a . py file is imported. They contain the “compiled bytecode” of the imported module/program so that the “translation” from source code to bytecode (which only needs to be done once) can be skipped on subsequent imports if the . pyc is newer than the corresponding .

How do I hide source code from public view in Python?

There are ways to ‘hide’ your Python source code:

  1. ship your application as .
  2. ship your application using a packager such as py2exe (or similar).
  3. Ship your application in.

How do I protect a .PY file?

The best solution to this vulnerability is to encrypt Python source code. Encrypting Python source code is a method of “Python obfuscation,” which has the purpose of storing the original source code in a form that is unreadable to humans.

Can you decompile a PYC file?

Yes, it is possible.

How do I edit a PYC file?

You cannot edit pyc files. A . pyc file is a compiled version of a . py file.

How do I stop Python from creating Pycache?

Suppressing the creation of __pycache__ Alternatively, you can set PYTHONDONTWRITEBYTECODE environment variable to any non-empty string. Again, this will prevent Python from trying to write .

Can I delete __ Pycache __?

First finds all __pycache__ folders in current directory. Execute rm -r {} + to delete each folder at step above ( {} signify for placeholder and + to end the command)

Can I remove __ Pycache __?

Explains: First finds all __pycache__ folders in current directory. Execute rm -r {} + to delete each folder at step above ( {} signify for placeholder and + to end the command)

How do I protect my Python source code?

Instead of converting some parts of the code to C, they hide the entire python code inside a protective C layer. Then, if they want a module importable by python, they write a thin python extension on top of the C. Open source is a much easier way of life.

Is there a way to hide source code?

JavaScript Encryption This is by far the most popular way to try to hide one’s source code. It involves taking your code, using a custom made function to “encrypt” it somehow, and then putting it in an HTML file along with a function that will decrypt it for the browser.
