Python 3 Essentials

Course Overview

An introductory and beyond-level practical, hands-on Python training course that leads the student from the basics of writing and running Python scripts to more advanced features.

Who Should Attend

Some programming experience in any language

Course Objectives

Throughout the course students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review. This course is “skills-centric”, designed to train attendees in core Python and web development skills beyond an intermediate level, coupling the most current, effective techniques with best practices. Working within in an engaging, hands-on learning environment, guided by our expert Python practitioner, students will learn to: • Create working Python scripts following best practices • Use python data types appropriately • Read and write files with both text and binary data • Search and replace text with regular expressions • Get familiar with the standard library and its work-saving modules • Use lesser-known but powerful Python data types • Create "real-world", professional Python applications • Work with dates, times, and calendars • Know when to use collections such as lists, dictionaries, and sets • Understand Pythonic features such as comprehensions and iterators • Write robust code using exception handling
