ValueError, please help! (Python) This seems so easy, but what am I doing wrong?

There was only a 15 second portion of the video prior to this exercise that covered .remove. I'm confused since it looks so different from what was in the video. I guess I'm just not understanding the syntax or the method.

Thank you in advance!

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

Are you ok with task 2?

I had received a message about you having trouble with that but I don't see it here.

Hi Daniel,

So in this first task you are being asked to remove the last item in the list. It's referring to the last item in the states list so you need to remove the 5.

The color list is a list within the states list. That entire list is considered an item or element of the states list.

If you did need to remove the "blue" then you have to access that list first and then call the remove method on that. That color list would be at index 1 within the states list.

So you could do

states[1].remove('blue')
