Python DRY Principle: Why Blindly Removing Duplication Breaks Code Abstraction
The DRY (Don't Repeat Yourself) principle dictates that duplication should be minimized specifically to eliminate redundant knowledge—such as data rules and business logic—rather than structural code elements like loops or control flow. Within software engineering, this theory establishes a boundary condition where over-abstraction by merging distinct logical domains into generic functions degrades maintainability through increased cognitive complexity. The core mechanism involves abstracting only duplicated constraints while intentionally preserving duplication in procedural steps to enforce architectural boundaries and decouple independent concerns.
