**1) Separation of Concerns (SOC)**

*   Divide your program into small, independent parts.
    
*   Each part should do one thing well.
    

**2) Document Your Code (DYC)**

*   Write as if your future self (or another developer) will thank you.
    
*   Add clear comments and documentation for complex logic.
    

**3) Don’t Repeat Yourself (DRY)**

*   Avoid duplicating code.
    
*   Reuse functions, modules, and libraries whenever possible.
    

**4) Keep It Simple, Stupid (KISS)**

*   Simple > Clever.
    
*   Readability always beats over-engineered solutions.
    

**5) Test Driven Development (TDD)**

*   Write a failing test first.
    
*   Implement the code to pass the test.
    
*   Refactor without changing behavior.
    
*     
    

**6) You Ain’t Gonna Need It (YAGNI)**

*   Don’t build features you “might” need someday.
    
*   Focus on what’s essential today.
    

🚀 Clean code isn’t just about elegance — it’s about building software that lasts.
