For example, If I have an list -

a = [10,2,3,5,17]

I want to tell python that I don't want the element 17 anymore and I want to remove that element and decrease the size of the array by 1.

I know python automatically frees all objects that are not referenced anymore, but how do I tell python that I don't want to use the last index anymore?

I basically want to make my program more memory efficient and remove all the extra space that I don't want dynamically.
