Once any() encounters an item that results in true from the lambda expression, any() is done. It no longer needs to examine the remaining items in the list. So, it returns true at that point.

This is one of the reasons why side effects are something to avoid when using functional programming. You do not know whether your side effect (e.g., printing the item) will be applied to every item or not.
