Software Design in Python - Cohesion and Coupling: Write BETTER PYTHON CODE Part 1

💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide. Writing code, especially in larger software projects can be very challenging. In this video, I'm going to cover cohesion and coupling to help you write better code. I'll go through a Python program in detail and I'll show you how to write code that has low coupling and strong cohesion. Coupling and Cohesion are part of the GRASP principles of object-oriented design, as proposed by Craig Larman in his book (see below for a link).
