Deleting ElementsDeleting Elements

Suppose we have a list of things to do:

This list has 3 elements.

Let's say that we completed the first thing from this list; that is, we have already written an email to Tom. To strike that element off the list, we write:

Now the list has two elements:

tasks[0] is 'call Max'

tasks[1] is 'meet with sister'

We can delete any list item by specifying its index number.


What about the syntax of the del?

  • The statement begins with the keyword del.
  • Then we usually specify the list item using index tasks[index].

It's time to practice!


You have the following list:

groups = ['The Beatles', 'The Band', 'The Clash', 'The Dillards', 'The Mamas and the Papas', 'The Kingston Trio']

You have to drop such elements from the list using positive indexing only: 'The Beatles', 'The Mamas and the Papas'.

If you're having trouble with which indexes to use to delete the elements, look at the hints.

Everything was clear?
