Question

我目前正在使用Python 3.4＆randrange函数构建一个小测验游戏。我有它设置并努力自动选择一个变量用于选择一个问题。我唯一的问题是，每次参加考试时，我怎样才能让它只使用一次这个问题。

#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。

Answer 1

你可以做一些类似于现实生活的事情：你手中有一套牌，随机洗牌，拿第一张，丢弃它，从牌组拿另一张等等。

在Python中，你可以通过使用问题列表，随机改组问题，然后逐个采集每个问题来做到这一点。

示例：

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

Answer 2

不是每次都选择一个随机数，而是尝试改组数字列表以随机化问题顺序：

from random import shuffle

# range creates a list: [1, 2, 3]
questions = range(1, 4)
shuffle(questions)

for q in questions:
    if q == 1:
        #question 1
    if q == 2:
        #question 2

为了不断改进您的程序，请考虑使用字典来存储您的问题，并编写一个函数来处理问题和答案部分。这样，您只需编写一次问题代码，就可以反复使用新问题。
