Deleting elements

There are several ways to delete elements from a list. If you know the index of the element you want, you can use pop:

                       

pop modifies the list and returns the element that was removed.

If you don’t need the removed value, you can use del operator:


If you know the element you want to remove (but not the index), you can use remove:

 

The return value from remove is None.

To remove more than one element, you can use del with a slice index:

 

As usual, the slice selects all elements up to, but not including, the second index.
