Summary
This hands on Python programming course shows how to rapidly develop and maintain effective Python programs.

Description/Agenda

This hands on Python programming course shows how to rapidly develop and maintain effective Python programs. The course includes thorough coverage of Python syntax, built in data types and control constructs. The course takes a practical approach to creating and organizing Python programs using functions, packages, modules and classes as part of Python's object-oriented paradigm. Attendees will learn to identify and correct problems through unit testing and exception handling. Attendees will use regular expressions to rapidly process data captured from users and from the file system.

Attendees will learn how to use Python to create scripts that manipulate data, automate tasks, perform error handling and store and retrieve data by using relational databases and XML files. Students will be able to create Python scripts that assist with system administration, web services and web applications. Students will learn how to create GUI based Python programs to gracefully interact with the user.

Comprehensive hands on exercises are integrated throughout to reinforce learning and develop real competency.

Course Prerequisites: Prior scripting experience or knowledge of fundamental programming concepts.
