Is it possible to make it impossible to deobfuscate the code?

Question

Python

Actually, the question is: how to pack the python code so that it becomes completely unreadable, without the ability to bring it into a readable form in adequate time - write your own obfuscator, or are there simpler solutions?

Answer 1

Somewhere I saw an obfuscator that replaced all identifiers with a string of underscores of different lengths - after this it becomes impossible to read the code. But in my opinion it was for JS. But I think it's not difficult to write your own either.
