我正在尝试构建 BlackJack 游戏。
程序启动，并使用随机模块生成 2 个不同的数字，告诉您您拥有哪张卡。
- 数字 1 是值，例如8
- 2 号是花色，例如4 = 黑桃
程序有时会给我 2 张卡片，而另一半时间会给我一张卡片。
问题:为什么这个程序没有按预期运行？
types = [" of Spades", " of Diamonds", " of Clubs", " of Hearts"]
special = ["King", "Queen", "Jack", "Ace"]
tries = 0
import random
import time
print("Welcome to BlackJack.")
time.sleep(1)
print("Let's Begin.")
time.sleep(1)
while tries < 1:
cardnumber1 = random.randint(2, 13)
random.shuffle(types)
random.shuffle(special)
cardnumber2 = random.randint(2, 13)
random.shuffle(special)
random.shuffle(types)
cardnumber3 = random.randint(2, 9)
random.shuffle(special)
random.shuffle(types)
cardnumber4 = random.randint(2, 9)
random.shuffle(special)
random.shuffle(types)
cardtype1 = random.choice(types)
random.shuffle(special)
random.shuffle(types)
cardtype2 = random.choice(types)
random.shuffle(special)
random.shuffle(types)
cardtype3 = random.choice(types)
random.shuffle(special)
random.shuffle(types)
cardtype4 = random.choice(types)
random.shuffle(special)
random.shuffle(types)
cardspecial = random.choice(special)
random.shuffle(special)
random.shuffle(types)
cardspecial2 = random.choice(special)
random.shuffle(special)
random.shuffle(types)
if cardnumber1 > 10:
print(str(cardnumber3) + cardtype1)
tries = tries + 1
if cardnumber2 > 10:
print(str(cardnumber4) + cardtype2)
tries = tries + 1
if cardnumber1 < 9:
print(cardspecial + cardtype3)
tries = tries + 1
if cardnumber2 < 9:
print(cardspecial2 + cardtype4)
tries = tries + 1
请您参考如下方法:
您可以完整地声明您的列表:
types = [" of Spades", " of Diamonds", " of Clubs", " of Hearts"]
cards = ["2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace"]
并创建一整套它们:
deck = [ (card, typ) for card in cards for typ in types] # create tuples
print (deck)
要抽一张牌:
card = random.choice(deck) # will return a tuple for 1 card, 1st value is face, 2nd is typ
deck.remove(card) # remove the card from the deck so you dont draw it again
face,typ = card # deconstruct tuple
print(face)
print(typ)
输出:
[('2', ' of Spades'), ('2', ' of Diamonds'), ('2', ' of Clubs'), ('2', ' of Hearts'),
('3', ' of Spades'), ('3', ' of Diamonds'), ('3', ' of Clubs'), ('3', ' of Hearts'),
('4', ' of Spades'), ('4', ' of Diamonds'), ('4', ' of Clubs'), ('4', ' of Hearts'),
('5', ' of Spades'), ('5', ' of Diamonds'), ('5', ' of Clubs'), ('5', ' of Hearts'),
('6', ' of Spades'), ('6', ' of Diamonds'), ('6', ' of Clubs'), ('6', ' of Hearts'),
('7', ' of Spades'), ('7', ' of Diamonds'), ('7', ' of Clubs'), ('7', ' of Hearts'),
('8', ' of Spades'), ('8', ' of Diamonds'), ('8', ' of Clubs'), ('8', ' of Hearts'),
('9', ' of Spades'), ('9', ' of Diamonds'), ('9', ' of Clubs'), ('9', ' of Hearts'),
('10', ' of Spades'), ('10', ' of Diamonds'), ('10', ' of Clubs'), ('10', ' of Hearts'),
('Jack', ' of Spades'), ('Jack', ' of Diamonds'), ('Jack', ' of Clubs'), ('Jack', ' of Hearts'),
('Queen', ' of Spades'), ('Queen', ' of Diamonds'), ('Queen', ' of Clubs'), ('Queen', ' of Hearts'),
('King', ' of Spades'), ('King', ' of Diamonds'), ('King', ' of Clubs'), ('King', ' of Hearts'),
('Ace', ' of Spades'), ('Ace', ' of Diamonds'), ('Ace', ' of Clubs'), ('Ace', ' of Hearts')]

deck = [ (card, typ) for card in cards for typ in types]
称为列表理解。这是一种从东西构造列表的方法——即范围、其他列表、迭代器、...
基本语法:
-
newList = [ str(x) for x in range(0,10)]将使用内置的 range(0,10) 创建从 0 到 9 的数字并将它们变成一个字符串并从中构建一个列表 - 链接到 doku:https://docs.python.org/3/tutorial/datastructures.html#list-comprehensions
我构建元组 (card, typ)对于 cards 中的每个元素(您的列表)和 types你的其他列表)。
[ (card, typ) for card in cards for typ in types]
# equivalent to
deck = [] # empty list
for card in cards:
for typ in types:
deck.append( (card,typ) ) # create tuples and add to list
你可以使用这副牌并 shuffle() 一次，然后从中取出 deck.pop() 牌(更快，只需要洗牌一次)或者每次随机抽取一张牌 random.choice(deck) 然后将其移除从甲板上。
参见 Lists对于列表中的方法。
参见 buildins - 你找到range()在该列表中，可以获得更多信息。
