From the creator

💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide. The strategy pattern is a widely used design pattern that help you write better Python code. I'll show you how to apply the strategy using a practical example written in Python. I'll cover both the classic object-oriented version of the pattern, and I'll also show you a functional version that's a bit shorter to write and works equally well. At the end of the video, there's a more advanced bit where you'll see how to add type hints for functions as parameters. 🎓 ArjanCodes Courses: https://www.arjancodes.com/courses.
