Hey Noor Hafiza Binti Ibrahim, you are very close!

The method pop() return the item popped and modified the list in-place. So newlist contains the popped item and not the new list. :point_right: change the returned item to list instead of newlist.

Also, it is not the best choice to use the name of a built-in type list as a variable name. This overrides the name locally to the function and prevents list() from working. Try using list1 or num_list, etc.

Post back if you need more help. Good luck!!
