python - 如何让 Python 3.4 只使用一次 randrange 变量？

Question

我目前正在使用 Python 3.4 的 randrange 函数构建一个小问答游戏。我已经设置好并可以自动选择一个变量来选择一个问题。我唯一的问题是如何让它在您每次参加考试时只使用一次问题。

#Main Game
def game():
    score = 0
    while True:
        irand = randrange(0,4)
        #Question 1
        if irand == 1:
            quiz += 1
            print ("What was the first Pokémon?")
            time.sleep(0.5)
            print ("[A] Bulbasaur")
            time.sleep(0.5)
            print ("[B] Pikachu")
            time.sleep(0.5)
            print ("[C] Nicki Minaj")
            time.sleep(0.5)
            print ("[D] Arceus")
            time.sleep(1)
            question1 = input ("Your Answer: ")
            if question1 == 'a':
                score += 1
                print ("Your answer is correct!")
                time.sleep(2)
                print ("Your score is now %s" % score + "!")
                time.sleep(4)
                cls()
                continue
            if question1 == 'b' or 'c' or 'd':
                print ("Your answer is incorrect!")
                time.sleep(4)
                cls()
                continue
        #Question 2
        if irand == 2:
            quiz += 1
            print ("What item shares experience with your party of Pokémon?")
            time.sleep(0.5)
            print ("[A] Exp Distributor")
            time.sleep(0.5)
            print ("[B] Exp Party")
            time.sleep(0.5)
            print ("[C] Exp Share")
            time.sleep(0.5)
            print ("[D] Exp Gain")
            time.sleep(1)
            question2 = input ("Your Answer: ")
            if question2 == 'c':
                score += 1
                print ("Your answer is correct!")
                time.sleep(2)
                print ("Your score is now %s" % score + "!")
                time.sleep(4)
                cls()
                continue
            if question2 == 'a' or 'b' or 'd':
                print ("Your answer is incorrect!")
                time.sleep(4)
                cls()
                continue
        #Question 3
        if irand == 3:
            quiz += 1
            print ("What Pokémon is the god Pokémon?")
            time.sleep(0.5)
            print ("[A] Arceus")
            time.sleep(0.5)
            print ("[B] Magikarp")
            time.sleep(0.5)
            print ("[C] Meowth")
            time.sleep(0.5)
            print ("[D] Pikachu")
            time.sleep(1)
            question3 = input ("Your Answer: ")
            if question3 == 'a':
                score += 1
                print ("Your answer is correct!")
                time.sleep(2)
                print ("Your score is now %s" % score + "!")
                time.sleep(4)
                cls()
                continue 
            if question3 == 'b' or 'c' or 'd':
                print ("Your answer is incorrect!")
                time.sleep(4)
                cls()
                continue
        #Quiz Ending
        if quiz == 20:
            print ("The quiz is now over.")
            time.sleep(2)

我还没有尝试过任何东西，因为我还在学习 Python。非常感谢任何帮助。

你可以做一些与现实生活中类似的事情:你手里拿着一组牌，随机洗牌，拿第一张，弃掉它，从牌堆中拿另一张，等等。

在 Python 中，您可以通过使用问题列表、随机打乱问题顺序，然后一次回答每个问题来做到这一点。

例子:

>>> import random
>>> cards = [1,2,3,4,5]
>>> random.shuffle(cards)
>>> cards
[3, 5, 2, 1, 4]
