A complete introduction to the Python Programming language

What you'll learn

Understand imperative, object-oriented and functional programming concepts

Build confidence writing Python scripts using modern Python 3 features

Learn how to use the IDE effectively to write and maintain code

Learn how to perform useful operations such file and network I/O


This Python course provides a complete introduction to programming using the Python scripting language. Your team will learn fundamental programming concepts and problem solving. All the important features of Python 3 will be explained using practical examples and exercises. Both the functional and object-oriented paradigms of Python are covered in depth, including best practices for using them in combination.

This course will allow delegates of any experience level to begin building automation scripts of their own. The pace and content can be tailored to meet your team’s specific needs.
