Refactoring vs Rewriting Code in Python: What's the Difference?

What’s the difference between refactoring and rewriting code in Python?

Refactoring involves improving the existing code's structure without changing its external behavior, while rewriting means starting from scratch.

When should I choose to refactor instead of rewriting?

You should refactor when the existing code is mostly functional but needs improvement for readability or maintainability. Rewriting is better when the code is too flawed or outdated.

Can you give me an example of when to refactor?

Sure! If you have a function that works but is overly complex and hard to understand, refactoring it into smaller, clearer functions can enhance maintainability.

What are the risks of rewriting code?

Rewriting code can introduce new bugs, lead to missed features, and often requires more time and resources than anticipated.

How do I decide which approach to take?

Evaluate the current code's quality, the time available, and the project's requirements. If the code is mostly sound, refactor; if it's fundamentally flawed, consider rewriting.
