A familiarity of Design Patterns will be very useful when planning, discussing, managing and documenting your applications from now on and into the future. A Design Pattern is a description or template that can be repeatedly applied to a commonly recurring problem in software design. This book focuses on the 23 famous GoF (Gang of Four) Design Patterns implemented in Python. I have also created and written hundreds of Open Source GitHub Repositories, Medium Articles and video tutorials on YouTube, Udemy and Skillshare. For over 20 years I have been an IT engineer building and managing real time, low latency, high availability, asynchronous, multi threaded, remotely managed, fully automated, monitored solutions in the education, aeronautical, banking, drone, gaming and telecommunications industries.
