Software Design in Python - The Factory Pattern in Python // Separate Creation From Use

💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide. In this video, I explain what the Factory pattern (or: Abstract Factory) is, and how to use it in Python. One of the greatest things about this pattern is that it allows you to separate creation from use. It's one of my most-used patterns.
