Write Cleaner Loops with List Comprehensions

In Python, you can often replace a multi-line loop that builds a list with a single, elegant line called a list comprehension. Instead of initializing an empty list and calling '.append()' inside a loop, you can write something like '[item for item in collection if condition]'. It’s not just shorter; it’s often faster because it’s optimized internally. Just remember the golden rule: readability first. If your comprehension starts spanning multiple lines or gets packed with nested logic, it’s probably better to stick with a traditional loop. Code is read much more often than it’s written, so don't sacrifice clarity for cleverness.
