How to implement tic-tac-toe over the Internet?

Question

Python

Good evening.
I wanted to write simple tic-tac-toe in a browser for two people in Python.
Basic moments:

1. Connection occurs via a specially generated link
   
2. Only 2 users can connect using the link at the same time.
   
3. After the game ends, the session is terminated and the link is no longer available
   
4. Dynamic Data Change
   
5. Well, actually the functionality of the game itself, how best to store and transfer data?
   

What can I read / watch on this topic? Perhaps there are already some simple tutorials to catch the essence.
