Totally stuck on .remove LIST with no good online answers.. Please help!

Can someone help me get past this one tiny hurdle? Take a look at my code and tell me what you think?

lists.py 
states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5,
states.remove(states[len(states) - 2])
states.remove(states[0])

Problem with index:

To remove last item you must remove 'len(LIST)-1' index element.

TO remove second element you must remove second-1=>List[1] element.

see the code for more detail.

states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5,
]
states.remove(states[len(states) - 1])
states.remove(states[1])

If you don't mind, can you explain some of the logic behind the answer?

we were told to remove the 2nd and last element of the list.

to remove the second element we remove the element at index 1, as indexing starts from 0.

for last element, we calculate the total length of the list using len(). and then subtracting one from it. so len(list_name)-1 index.

finally we use remove function to remove the item specified in the argument-list of remove function.
