Is it possible to set the time before deleting a value from a variable?

Question

Python

There is a variable with user id, is it possible to somehow set the time after which a certain id will be deleted from the variable?

Answer 1

Well, you can wrap the function in a thread that will walk as a demon and clear the necessary variables.

Answer 2

you probably need to keep track of the time it was added to the list, that is, add not only the ID but now ()
and then check at the right points and, if necessary, delete the old ones.
you can do cleaning in a separate thread, depending on what kind of task
