Bummer: Uh oh, I didn't get the correct value returned. It should have been [5, 6, 7, 9]. Instead, it was 8

pop.py 
# enter your code below
def pop(list, index):
    try:
        newlist = list.pop(index)
        return newlist
    except IndexError as error:

Hey Noor Hafiza Binti Ibrahim, you are very close!

The pop() method operates on a list in-place and returns the popped item. So newlist will contain the popped item and list will be the modified list. :point_right: change to return list to pass the challenge.

BTW, using the name of a built-in list as a variable name overrides its definition locally. So list() would no longer work with the function. Alternative names could be num_list, list1, etc.

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