In this workshop, we will do basic network programming in python! Python handles network connections via sockets Which can be bounded to an application by a hostname and a port number. The goal of the workshop is to learn about how sockets are created, connected to and closed in python. We start from a simple client server application and Gradually Develop a multi-threaded server Which is capable of handling multiple connections simultaneously from clients with the help of threads.

Like previous workshops, the  examples and assistance we give will follow python version 3.  We expect students to write code Their Also in version 3. If for some reason you insist is using version 2, you have to make a clear comment about it in every piece of code you return.

Material to be used: 

• Exercises for the workshop session:  https://www.cs.helsinki.fi/u/owaltari/distsys/ws2/dist_sys_ws2.html
• Model answers for workshop exercises 2: https://www.cs.helsinki.fi/u/owaltari/distsys/ws2/model_answers/
• Tutorial for Socket Programming in Python:  https://www.tutorialspoint.com/python/python_networking.htm 
• Python documentation for socket programming:  https://docs.python.org/2/howto/sockets.html

Note: Unfortunately the two latter links follow Python ver. 2 syntax. Pay attention especially to print function's syntax in case you want to just copy & paste the example code.

In this course we use python for all programming exercises!  The goal of the first workshop is to get everyone familiar with python. We start from the very basics of how to Invoke python code and write functions That use basic data structures and file system I / O. In case you have written a python in the past, you probably Already know all of the things covered in this workshop.

Workshops, examples and assistance we give will follow python version 3. We expect students to write code Their Also in version 3. If for some reason you insist is using version 2, you have to make a clear comment about it in every piece of code you return.

The workshop is held in a classroom with computers, Which have a version of Python 3 Already installed.  In case you're bringing your own laptop, it is Strongly Encouraged That you have Python installed Already in advance. Either download it from  https://www.python.org/downloads/  or look for it in your operating system's own repositories.
