calling a the .remove() method on an object two times

Why is my code wrong? How can this be done in a neat and concise way? Thank you.

states = ['active', 'inactive', ['red', 'blue', 'green'], 'cancelled', 'finished',5] print(states) states.remove(5).remove('active') print(states)

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

your code goes wrong because you can remove only one item at a time

Thank you. =)

But how about this?

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