I Have a TestServer, that asking questions to its client then collects answers. How to encode test's questions in txt file?(.py)

Question

I have an idea for it's solution:
[some_unique_control_symbols]bytes_at_test[another_unique_symbols]quest_number[another_control_symbols]Test's TEXT[another_control_symbols]Right_Answer;Wrong_Answers[control_symbols]... another qwestion, ..., [ending_control_symbols].
Maybe there is a better way?
Testing has made in python3 on PyQt5 (and there's import socket, import threading), but I need your advise for algorhythm of encoding , not the source code. Have you got some ideas?

Unique symbols: $$^*** etc.

Answer 1

Maybe tets.txt need to be encrypted?
