Removing ElementsRemoving Elements

Imagine you have this list:

You can also remove an item from the list by specifying its value. Here's how to do that.

Now, the list is down to two items instead of three:

  • tasks[0] reads 'email Ann';
  • tasks[1] reads 'meet with classmates'.

Note

With the remove() method, you can only take out one item at a time.

Task

You've got this list:

numbers = [10, 12, 14, 16, 18, 20]

Your goal is to end up with:

numbers = [12, 14, 16]

Everything was clear?
