Write a set of Python classes that can simulate a messaging application in which
one party, Ali, is randomly creating a set of messages that he wants to send to
Veli. A Server process is continually checking if Ali has any messages to send,
and if so, it delivers them to Veli’s phone, and Veli is periodically checking if his
phone has a message from Ali, and, if so, he reads, displays and answers it.
 

Hint: Use three different classes, for Ali, Veli and Server, and provide methods
that perform their various tasks, as well as a simulator engine that performs the
random messaging
