code refactoring: 6 best practices with rapidops & code examples

code refactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior. it's about improving the internal structure of your code to make it cleaner, more efficient, maintainable, and easier to understand. while it doesn't add new features, refactoring significantly impacts the long-term health and development speed of a project. this tutorial will explore six best practices for code refactoring, incorporating the concept of "rapidops" – a philosophy of making small, frequent changes – and providing illustrative code examples in python.

**best practice 1: start small and iterate (rapidops)**

avoid large-scale refactoring efforts. instead, focus on small, manageable changes. each refactoring should be a tiny, self-contained improvement. this makes it easier to track progress, identify and fix errors, and revert changes if necessary. this iterative approach aligns perfectly with the rapidops philosophy.

**example:** let's say you have a function that does too much:

instead of rewriting the entire function at once, break it down step-by-step:

**iteration 1:** extract data cleaning into a separate function:

**iteration 2:** extract data validation:

continue this process, extracting each step into its own function until `process_data` becomes concise and focused.

**best practice 2: write unit tests before refactoring**

before you start refactoring, ensure you have comprehensive unit tests covering the existing functionality. this protects against introducing bugs during the refactoring process. if a test fails after a refactoring change, you know immediately that you've broken something.

**example (using `unittest`):**

**best practice 3: refactor one thing at a time**

focus on a single refactoring goal per iteration. trying to tackle multiple issues simultaneously increases the complexity and the risk of introducin ...
