Solid

SOLID Principles: A Complete Deep Dive Prerequisite: Working familiarity with Python object-oriented programming, specifically classes, objects, inheritance, method overriding, polymorphism, and abstract base classes. If any of those terms are unfamiliar, study the OOP document first, because every argument in this document is expressed in that vocabulary. What this document delivers: A rigorous treatment of the five SOLID principles. For each principle you will find its formal statement, a precise interpretation of every term in that statement, the concrete engineering problem it solves, a worked example of the problem and its resolution, the alternative techniques available for the same goal, the costs of applying the principle, and the conditions under which it should not be applied. ...

SOLID Principles: Practice Workbook Prerequisite: 02_solid_principles.md. This workbook assumes the five principles have already been defined and demonstrated. It contains no new theory. Its purpose is to convert conceptual knowledge into diagnostic skill. Table of Contents How to Use This Workbook Vocabulary and the Diagnostic Method Section A: Recognition Drills Section B: Single Responsibility Principle Section C: Open/Closed Principle Section D: Liskov Substitution Principle Section E: Interface Segregation Principle Section F: Dependency Inversion Principle Section G: Combined Violations Section H: Capstone Refactor Self-Review Checklist Summary and Key Takeaways Appendix: Violation Signature Reference 1. How to Use This Workbook 1.1 What this document is for Knowing the definition of the Single Responsibility Principle and being able to detect a Single Responsibility violation in unfamiliar code are two different competencies. The first is declarative knowledge and can be acquired by reading. The second is a diagnostic skill and can only be acquired by repeated exposure to examples, followed by correction. ...
