I have seen code that just created a list comprehension to iterate over something but was discarding the results.
If you mean, discard the resulting list, that is probably bad code as it should not create the list in the first place. A generator expression or for loop will iterate without creating an unneeded list.

Just having a function that does nothing
Not possible. None is the default return. Python does not have proceedures, and that is not going to change, especially for a null proceedure.
