When you need to transform a list, skip the boilerplate of creating an empty array and running a `for` loop. Python's list comprehensions are not just more concise; they're often faster too. Instead of five lines of code, you can do something like `[item.upper() for item in my_list if item.is_valid]`.

It’s a great way to make your logic more declarative and easier to scan at a glance. Just be careful not to nest them too deeply—if a comprehension spans multiple lines or involves complex logic, a standard loop is still your best friend for keeping the code maintainable for the next developer who reads it.
