爲什麼我的程序會重複

Question

我試圖創建一個遊戲，在這個遊戲中你可以找到某些東西，但是當它產生新的項目時，它總是重複一個，我不知道爲什麼。所以任何解決方案將不勝感激。謝謝

import random 
cards=["3","helicopter","skip","chimmney","balloon","plane","bridge"] 
while list is not []: 
    card1=random.choice(cards) 
    cards.remove(card1) 
    card2=random.choice(cards) 
    cards.remove (card2) 
    print "card 1 = ",card1 
    print "card 2 = ",card2 
    choice=raw_input("type the card that you have found: ") 
    if choice ==card1: 
     card1=random.choice(cards) 
     print "card 1 = ",card1 
    else: 
     card2=random.choice(cards) 
     print "card 2 = ",card2 

Answer 1

您的程序會導致無限循環，因爲它的工作原理直到數組爲空，但您永遠不會從中刪除所有對象。

import random 
cards=["3","helicopter","skip","chimmney","balloon","plane","bridge"] 
running = True 
while running: 
    card1=random.choice(cards) 
    cards.remove(card1) 
    card2=random.choice(cards) 
    cards.remove (card2) 
    print "card 1 = ",card1 
    print "card 2 = ",card2 
    choice=raw_input("type the card that you have found: ") 
    if choice ==card1: 
     card1=random.choice(cards) 
     print "card 1 = ",card1 
     running = False 
    else: 
     card2=random.choice(cards) 
     print "card 2 = ",card2 
     running = False
