Using the del statement is relatively straightforward: it's used to delete something. Often it's used to remove an item from a list by referring to the item's index rather than its value. For example, if you have the following list:
list = [4, 8, 2, 3, 9, 7]
And you want to remove the number 9, which has an index of 4, because it is the 5th item in the list (index starts at 0), you could do so using the del statement, like this:
So your list will now look like this:
list = [4, 8, 2, 9, 7]
