Which task are you on? For task 1, you need to "remove the last item from the list". Then for task 2, you sill need your task 1 code there but you will add more after it.

In all multi-task challenges, each task builds on the work done before. So unless the instructions say otherwise, anything you write for a task will remain as-is as you continue to add to it for the other tasks.

Hi Ikechukwu,

The first exercise wants you to remove the last list item and the second exercise wants you to remove the second list item.

Are you on the second exercise? You'll have to remove the 5 first and then your code will work

Cheers!
