Practical Introduction to Python Development

Python is a very popular open-source, high-level programming language used for a broad assortment of programming tasks. This course is designed to introduce best practices in Python development, and to build a strong foundation for students to go on to use Python in creating one-off utilities, processing data, creating automated test scripts, machine learning, and web development. A balanced mixture of theory and labs demonstrate practical usage of Python and are designed to give students real-world understanding and experience.

Audience Profile

Those with experience with basic programming concepts such as loops and variables.

Prerequisites

Students should know how to navigate the Windows operating system. Ideally students already have some understand variables, functions and for loops - but demos and guidance will be given to help them to achieve a working application.
