What are some examples of the DRY principle in software development?

The DRY principle stands for 'Don't Repeat Yourself.' It emphasizes reducing repetition in code. For example, using functions to encapsulate repeated logic is a common practice.

Can you give me a specific code example?

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

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

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

What are the benefits of following the DRY principle?

Following the DRY principle helps in maintaining code, reduces the risk of errors, and makes it easier to update functionality without affecting multiple places in the code.

Are there any drawbacks to the DRY principle?

Yes, if taken to the extreme, it can lead to over-abstraction, making the code harder to understand. It's important to find a balance.
