如何保护 Python 源代码，同时使文件可供运行？

Question

So, I recently made a Python program that I want to send to someone with them being able to execute it, but not read the code I have typed in it. Any ideas how to do it?
BTW, I want it to be irreversible, except when reversed by me
In short, here are my Parameters:

1. Should remain a Python file
2. Can't be reversed, except by me
3. Code should not be readable
4. Should still have the ability to be run

Answer 1

The criteria you've posted are inconsistent. Python is an interpreted language. The entity running the language (ie Python interpreter) is reading your code and executing it, line by line. If you wrap it up to send to someone, their Python interpreter must have read permissions on the file, whether it's source code or "compiled" Python (which is easily decompiled into equivalent source code).

If we take a wider interpretation of "send to someone", there may be a business solution that serves your needs. You would provide your functionality , rather than the code: deploy it as a service from some available server: your own, or rented space. To do this, you instead provide an interface to your functionality.

If this fulfills your needs, you now have your next research topic.
