Course PYT105
Python Network Programming Using the Python Twisted Framework

Duration: 3 Days

Synopsis

This course will cover the installation, configuration, development and of the Twisted Framework and how to use it to implement TCP/IP based client server applications.

Case studies will include:

• Applications to access web pages and web services using the HTTP protocol
• Implementation of specialist web servers
• Implementing applications for sending and receiving email using POP, IMAP and SMTP protocols
• Developing specialist web services based on XML-RPC and SOAP
• Implementing custom SSH clients and SSH servers
• Implementing authentication mechanisms

Approximately 60% of the course will be devoted to instructor led presentations and 40% will be devoted to hands on lab work. The more complex case studies will be associated with lab work involving adapting and modifying their detailed functionality.

The main goal of the course is to provide a starting point for those wishing to implement specialist applications of their own.

Prerequisites

• Attendees are expected to be experienced Python programmers with some experience of web application development using HTML / XHTML, CSS , and JavaScript, a basic understanding of XML, and a basic understanding of TCP/IP sockets Programming.
