1216. Define a card suit

You get any card as an argument. Your task is to return the suit of this card (in lowercase).

Our deck (is preloaded):

DECK = ['2S','3S','4S','5S','6S','7S','8S','9S','10S','JS','QS','KS','AS',
        '2D','3D','4D','5D','6D','7D','8D','9D','10D','JD','QD','KD','AD',
        '2H','3H','4H','5H','6H','7H','8H','9H','10H','JH','QH','KH','AH',
        '2C','3C','4C','5C','6C','7C','8C','9C','10C','JC','QC','KC','AC']

('3C') -> return 'clubs'
('3D') -> return 'diamonds'
('3H') -> return 'hearts'
('3S') -> return 'spades'

Solution:

def define_suit(card):
    return {"C": "clubs", "D": "diamonds", "H": "hearts", "S": "spades"}[card[-1]]
