Question

import collections from random import choice Card = collections.namedtuple('Card',['rank', 'suit']) class FrenchDeck: ranks = [str(n) for n in range(2,11)] + list('JQKA') suits = 'spades diamonds clubs hearts'.split() def __init__(self): self._cards = [Card(rank, suit) for suit in self.suits for rank in self.ranks] def __len__(self): return len(self._cards) def __getitem__(self, position): return self._cards[position] suit_values = dict(spades=3, hearts=2, diamonds=1, clubs=0) def spades_high(card): rank_value = FrenchDeck.ranks.index(card.rank) return rank_value * len(suit_values) + suit_values[card.suit] deck =FrenchDeck() for card in sorted(deck, keys=spades_high()): #doctest: +ElLIPSIS print(card) 代码如上 nameerror name spades high is not defined
