remove() removes the first matching value or object. It does not do anything with the indexing. It just searches the object and deletes it. Example : myList = [4, 2, 3, 2] myList.remove(2) print(myList) This gives the output as [4, 3, 2]. It removed the 2 which occurred first. To remove all the 2's from the list you need to run a loop. del() removes the item at a specific index. It is helpful for deleting all elements or a slice. Example : myList = [4, 3, 3, 2] del myList[1] print(myList) This gives the output as [4, 3, 2]. The 3 at index 1 is removed from the list. Hope this clearly explains the difference !!

There is also a pop() method, which removes items from a certain index. myList.pop(3) equals: del myList[3] But it is rather matter of taste which you prefer to use. del myList[3] seemed to be slighty faster, operations are typically faster than methods.
