Mastering Python's For-Loop Else Block

Your Python for-loops are missing a secret weapon: the else block. I'm not talking

about an if-else inside the loop. I mean an `else` attached directly to the `for` loop

itself. This special `else` block only runs if the loop completes its entire sequence

without ever hitting a `break` statement. Think about searching for an item in a list.

You loop through, and if you find it, you `break`. But what if you

never find it? Instead of using a messy flag variable, just add an `else` block.

It will execute only when the loop finishes naturally. It’s the perfect, clean way to handle

a "search complete, but not found" case.
