Is there ever a reason you will need del?

Question

Won't most objects simply go out of scope or be lost when their reference is reassigned? Is del more important for multithreading?

Answer 1

Suppose you have a database of list of students..
With new admission you'll need to include their details..
If some students leave the institute, "del" comes in handy..

Answer 2

Let's say you have an file object that is outdated or not called upon for its value and for whatever reason never will be again this would be an good use for __del__ .
