In this course, you’ve learned when to use classes in your code. This knowledge is just as important as knowing how to write a class with attributes and methods. You’ve even learned about alternatives to inheritance.
SOLID is an acronym for five principles that you should use when thinking about object-oriented code. After this course, you’re well versed in the principles:
- The Single-Responsibility Principle (SRP)
- The Open-Closed Principle (OCP)
- The Liskov Substitution Principle (LSP)
- The Interface Segregation Principle (ISP)
- The Dependency Inversion Principle (DIP)
This course is the third in a three-part series. Part one is an introduction to class syntax, where you learn how to write a class and use its attributes and methods. Part two is about inheritance and class internals.
