How can I implement the DRY principle in my code?

How can I implement the DRY principle in my code?

The DRY principle stands for 'Don't Repeat Yourself.' It encourages reducing code duplication. You can implement it by creating functions or classes for repeated code segments.

Can you give me an example of applying DRY in a Python program?

Sure! Instead of writing the same code to calculate the area of a rectangle multiple times, you can create a function:

def calculate_area(length, width):
    return length * width

Then, call this function whenever you need to calculate the area.

What if I have a large codebase? How do I start refactoring?

Start by identifying repeated code blocks. Use tools like linters or code analysis tools to help find duplicates. Then, refactor those blocks into functions or classes.

Are there any tools that can help with DRY implementation?

Yes! Tools like SonarQube, ESLint, and PyLint can help identify code smells and duplication, making it easier to apply the DRY principle.
