Become a Python expert with the help of detailed discussions, illustrated with concrete examples

In Detail

Python is one of the most powerful, flexible, and popular programming languages in the world. Even though Python programs are simple to work with, writing code that is efficient, maintainable, and reusable can be a little tricky for some. The presence of Python’s “batteries included” toolbox allows you to easily produce application prototypes or implement new algorithms with minimum efforts.

This course takes you on a journey from the basics of operating in a Python development environment through to advanced topics and master-level techniques. It presents you with a guide to Python and its standard library, focusing on language and library elements that are particularly useful for tool authors and system programmers.

We start off with the basics to set up a functioning environment, creating packages, and running them on the command line. Through our journey, we’ll highlight the major aspects of managing our Python development environment, handling parallel computation, and mastering asynchronous I/O for improved performance of our system. Finally, we’ll learn the secrets of metaprogramming and unit testing in Python arming you with the perfect skillset to be a Python expert.

Mastering Python will get you up to speed in everything from basic programming practices to high-end tools and techniques that will help you set apart as a successful Python programmer.
