Course 589:
Python Programming Essentials

(4 days)

 

Course Description

Python is a powerful, portable, object-oriented, open source programming language. This course starts by quickly covering the basic: variables, control of flow, functions, modules, packages, and standard libraries. OO programming in Python is covered using a test first methodology. The course then takes an in-depth look at data structures and exception handling. Coverage includes higher-level Python programming concepts such as iterators, generators, file and database IO, and performance issues. This class is approximately 65% hands-on.

Note: This course uses Python 3.7 and can be taught on Linux and Microsoft Windows.
