Resources to learn about servers on Ubuntu?

Question

Python

Good!
I want to try to create a client-server application in python, but I have zero experience in this. More than Windows did not see anything. Here I rented a simple VDS server on Ubuntu for experiments, downloaded the putty program and was able to access it, and then I don’t know anything. Tell me where to study?
