Removing the last `N` elements of a list can be tricky at times.

Suppose I have the following list.

``````lst = [1, 2, 3, 4]
``````

## Remove last `N` elements by slicing

Most of us know that we can use `-1` to get the last element of a list. Similar, we can use the slice notation along with negative index to remove the last element.

``````print(lst[-1])  # 4
print(lst[:-1]) # [1, 2, 3]
print(lst)      # [1, 2, 3, 4]
``````

Note that this will create a shallow copy of the list. We can remove the last `N` element of a list like so:

``````lst = lst[:-n]
``````

But, this actually does not work when `n == 0` because it results in this operation, which will grab nothing from the list.

``````print(lst[:-0]) # []
``````

We can circumvent this by slicing with `-n or None`, which will evaluate to `-n` when `n > 0` and `None` when `n == 0`.

``````lst = lst[:-n or None]
``````

## Remove last `N` elements using `del`

If we don’t want to reassign the list, we can directly modify the original list with `del`.

``````del lst[-1:]
print(lst]) # [1, 2, 3]
``````

To remove the last `N` elements in a list, we can do the following:

``````del lst[-n:]
``````
