Hiding code or blocking code editing in Python

Question

I developed a software in Python and this software has some user's restrictions. Once I don't know how to block my users to open and change my code, it becomes very useless if they just delete a line from my code and then have permissions that they are not allowed. Is there any way to protect my software from changing or even block the code visualization?

Answer 1

Distribute only your Python compiled .pyc files.

Do not distribute your Python source code .py files.
