How do you correct this invalid list using .remove() method on last item of the list?

So far I've added states.remove($) in attempt to remove the last item. I'm currently receiving syntax error for "states.remove($) I've tried adding a space "states.remove ($) Where did I go wrong?

lists.py 
states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5,
]
states.remove($)

remove() takes the value that you want to remove so it'd have to be:

states.remove(5)

or if you didn't know the value of the last entry, you'd have to reference it by index using:

del states[-1]

Yikes, I thought the 5 was a dollar sign. I appreciate you taking the time to break the concept down. Thanks!

If you only intend to remove the last item in the list, you can use the pop() function on the list like this;

 states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5,
 ]
 states.pop()
