Clean code is essential for maintainable, scalable, and readable software. Here are some key principles to follow:

1. Meaningful Names

Use descriptive names for variables, functions, and classes.

  • Variables: user_name instead of uname
  • Functions: calculate_total_price() instead of calc()
  • Classes: UserRepository instead of Repo
clean_code

2. Keep Functions Small

A function should do one thing and do it well.

  • Split complex logic into smaller, focused functions
  • Aim for functions under 20 lines of code

3. Avoid Code Duplication

Repetition increases maintenance costs.

  • Use helper functions or refactoring
  • Follow DRY (Don't Repeat Yourself) principle

4. Write Self-Documenting Code

Code should be clear without excessive comments.

  • Use meaningful names and structure
  • Comments should explain why, not what

5. Format Consistently

Consistency improves readability.

  • Follow style guides (e.g., PEP 8 for Python)
  • Use proper indentation and spacing

6. Handle Errors Gracefully

Avoid silent failures.

  • Use try-catch blocks for exceptions
  • Log errors and provide meaningful feedback

7. Test Your Code

Unit tests ensure code reliability.

  • Write tests for edge cases
  • Use testing frameworks like Jest or PyTest
