全球名稱'排名'未定義

Question

我是Python新手，遇到此代碼的問題。等級和套裝在方法洗牌中不起作用。我的「簡單」（？）問題是，爲什麼？

from Tkinter import * 
from Canvas import Rectangle, CanvasText, Group, Window 
from PIL import Image 
import ImageTk 


win = Tk() 
text = Text(win, width=65, height=15, font=("Arial", 10)) 
win.title("Play High or Low Card") 
win.geometry("700x600") 

class Card(object): 

    RANKS = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"] 

    SUIT = ["Python/projekt/bilder/hearts.png", "Python/projekt/bilder/spades.png", "Python/projekt/bilder/diamond.png", "Python/projekt/bilder/clubs.png"] 

    def __init__(self, rank, suit): 
     self.rank = rank 
     self.suit = suit 

    def __str__(self): 
     rep = self.rank + self.suit 
     return rep 

    def draw(self,suit,rank): 

     bg = ImageTk.PhotoImage(Image.open(self.suit).resize((10, 10))) 

     cardGraph = Canvas(win, width=70, height=100, bg="White", bd=1, relief='solid', highlightthickness=2) 
     cardGraph.photo=bg 

     cardGraph.create_image(10,10, image=bg, anchor=CENTER) #left/up 
     cardGraph.create_image(53,93, image=bg, anchor=CENTER) #right/down 

     cardGraph.create_text(20, 10, text=self.rank, font=("Helvetica", 8, "bold")) #left/up 
     cardGraph.create_text(63, 93, text=self.rank, font=("Helvetica", 8, "bold")) #right/down 
     cardGraph.create_text(36, 50, text=self.rank, font=("Helvetica", 12, "bold")) #middle 

     cardGraph.pack(side = "left", anchor=NW) 

class Hand(object): 
    def __init__(self): 
     self.cards = [] 

    def __str__ (self): 
     if self.cards: 
      rep = "" 
      for card in self.cards: 
       rep += str(card) + " " 
     else: 
      rep = "<empty>" 
     return rep 

    def clear(self): 
     self.cards = [] 

    def add(self, card): 
     self.cards.append(card) 

    def give(self, card, other_hand): 
     self.cards.remove(card) 
     other_hand.add(card) 

class Deck(Hand, Card): 

    def populate(self): 
     for suit in Card.SUIT: 
      for rank in Card.RANKS: 
       self.add(Card(rank, suit)) 
       DrawCard = Card(rank,suit) 
       DrawCard.draw(self,rank) 

    def shuffle(self): 
     import random 
     random.shuffle(self.cards) 
     DrawCard = Card(rank,suit) 
     DrawCard.draw(self,rank) 

    def deal(self, hands, per_hand = 1): 
     for rounds in range(per_hand): 
      for hand in hands: 
       if self.cards: 
         top_card = self.cards[1] 
         self.give(top_card, hand) 


       else: 
        print("Cant continue deck. Out of cards!!") 



deck1 = Deck() 
deck1.populate() 
deck1.shuffle() 

my_hand = Hand() 
your_hand = Hand() 
hands = [my_hand, your_hand] 

deck1.deal(hands, per_hand = 5) 

print(my_hand) 


shuffleBtn = Button(win, text="Turn", command=lambda: deck1.shuffle()) 
shuffleBtn.pack() 

mainloop() 

回溯是： 你似乎期望他們在洗牌存在

Traceback (most recent call last): 
    File "C:/Users/RaJ/Desktop/Cards", line 95, in deck1.shuffle() 
    File "C:/Users/RaJ/Desktop/Cards", line 77, in shuffle 
    DrawCard = Card(rank,suit) 
NameError: global name 'rank' is not defined 

Answer 1

點數和花色都在甲板類未知。 我認爲你應該在洗牌之後抓取第一張牌，而不是試圖創建一張新牌。即

def shuffle(self): 
     import random 
     random.shuffle(self.cards) 
     DrawCard = self.cards[0] 
     DrawCard.draw() 

和class卡應該修改爲不通過套裝和等級劃分，它們不被使用。使用self.rank和self.draw。

def draw(self): 

是所有在該類
