💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide. In this video, you'll learn how to write better Python code using dependency inversion by going step by step through a simple code example. Dependency inversion is one of the five SOLID principles. The basic idea of dependency inversion is to write your code in such a way that high level modules shouldn't depend on low level modules, both should depend on abstractions (i.e. abstract classes and interfaces). 🎓 ArjanCodes Courses: https://www.arjancodes.com/courses.
