In this video I talk about software architecture, what it is and how it relates to writing code and designing software. As an example, I show you how to implement a Model-View-Controller (MVC) architecture in Python and also discuss a few other software architectures.

Here's my FREE 7-step guide to help you consistently design great software: https://arjancodes.com/designguide.
