Master S.O.L.I.D. Design Principles in Python

Target Audience

Students who benefit from this course are:

• Developers who want clear, concise code examples that demonstrate how SOLID principles improve software design.
• Python programmers looking to apply SOLID principles effectively in real-world Python projects.
• Programmers interested in understanding how SOLID principles relate to object-oriented programming (OOP).

Course Lessons

Introduction	Course introduction, introduction to the five S.O.L.I.D. design principles.
Dependency Inversion Principle	High level modules should not depend on low level modules. Instead, they should depend on abstractions, Concrete classes are volatile, Depending on concrete classes breaks the Open-closed principle.
Interface Segregation Principle	No client should be forced to depend on methods it does not use, from "Fat" interfaces to "Slim" interfaces.
Liskov Substitution Principle	Subclasses should not change the behavior of superclasses in unexpected ways, Selecting on types, Break the is-a relationship, Raise error in overridden method.
Open-Closed Principle	Open for extension but closed for modification, Selecting on types, Safely Extend and Remove functionality.
Single Responsibility Principle	Things should have only one reason to change, Mixing Responsibilities, Dependencies on libraries.
Conclusion	Course conclusion, your next steps after this course.

By the end of this course, you will be able to:

• Recognize which parts of you code can be improved by applying the SOLID principles.
• List the 5 SOLID principles and describe their purposes.
• Use the compact code examples from this course as blueprints to optimize your existing code.
