这是我第一次在这个网站上寻求帮助。我在这里寻找答案,但没有什么能真正为我清除。
我正在努力学习 Python。我在“类”一章。以下代码:
class Character:
def __init__(self, name, initial_health):
self.name = name
self.health = initial_health
self.inventory = []
def __str__(self):
s = "Name: " + self.name
s += "| Health: " + str(self.health)
s += "| Inventory: " + str(self.inventory)
return s
def grab(self, item):
self.inventory.append(item)
me = Character("vic", 37)
me.grab("pencil")
me.grab("paper")
print str(me)
...产生:
Name: vic| Health: 37| Inventory: ['pencil', 'paper']
但是下面的代码在我看来非常相似,它打印出内存位置而不是变量本身:
import random
SUITS = ['C', 'S', 'H', 'D']
RANKS = ['A', '2', '3', '4', '5', '6', '7', '8', '9', 'T', 'J', 'Q', 'K']
VALUES = {'A':1, '2':2, '3':3, '4':4, '5':5, '6':6, '7':7, '8':8, '9':9, 'T':10, 'J':10, 'Q':10, 'K':10}
# define card class
class Card:
def __init__(self, suit, rank):
if (suit in SUITS) and (rank in RANKS):
self.suit = suit
self.rank = rank
self.value = self.get_value()
else:
print "Invalid card: " + str(suit) + str(rank)
def __str__(self):
return str(self.suit) + str(self.rank)
def get_cardDetails(self):
return self.suit + self.rank + ": " + str(self.value)
def get_suit(self):
return self.suit
def get_rank(self):
return self.rank
def get_value(self):
value = VALUES[self.rank]
return value
class Hand:
def __init__(self, card1, card2):
self.cardCount = 0
self.cards = []
self.cards.append(card1)
self.cardCount += 1
self.cards.append(card2)
self.cardCount += 1
self.value = self.get_value()
print "Dealed hand: " + str(self.cards[0]) + str(self.cards[1])
print "Dealed hand: " + str(self.cards)
def __iter__(self):
return iter(self.cards)
def __str__(self):
return str(self.cards)
def get_details(self):
print "Hand: "
for each in self.cards:
print " -" + str(each) + ": " + str(each.value)
s = "Cards: " + str(self.cardCount) + \
" | Hand: " + str(self.cards) + \
" | Total Value: " + str(self.value) + " |"
return s
def add_card(self, card):
self.cards.append(card)
self.cardCount += 1
self.value = self.get_value()
print "Added: " + str(card)
def get_value(self):
value = 0
for each in self.cards:
value = value + each.value
return value
c1 = Card("C", "2")
c2 = Card("C", "3")
h = Hand(c1, c2)
print str(h)
输出:
Dealed hand: C2C3
Dealed hand: [<__main__.Card instance at 0x00E4F558>, <__main__.Card instance at 0x00E543C8>]
[<__main__.Card instance at 0x00E4F558>, <__main__.Card instance at 0x00E543C8>]
我确定我一定在这里遗漏了一些东西——毕竟我只是在学习这个。任何帮助将不胜感激。提前致谢。对不起,很长的帖子。
