Question

我正在做的是从20个池中生成五个问题。因此，为了生成这五个问题，我使用了随机函数。它在大多数情况下都能正常工作，但有时会在五个问题中重复同样的问题。在代码正常运行的60％的时间内，它确实会生成随机问题，仅几次将同一问题重复两次。我该如何改善呢？

import random

questions = ["Traditional Maori food cooked in an earth oven: ",
         "Type in the Maori word for 'cave': ",
         "Something you eat to fill your belly: ",
         "What is 'Sun' in Maori: ",
         "A challenge laid down in chant and dance: ",
         "Visitor or guest: ",
         "A gathering, meeting, or assembly: ",
         "Funeral ceremony: ",
         "If you gave a donation, gift, or contribution, you would have given a...: ",
         "Maori word for 'Mountain': ",
         "What is 'Water' in Maori: ",
         "How do you greet in Maori like 'Hi, G'Day': ",
         "'Merry Christmas' in Maori: ",
         "Word for 'Winter' in Maori: ",
         "'Good Morning' in Maori: ",
         "Word 'Family' in Maori: ",
         "The most popular sport -'Rugby': ",
         "Word in Maori for 'Chicken': ",
         "'I am tired' in Maori: ",
         "Maori name for 'New Zealand': ",
          ]

answers = ["hangi", "ana", "kai", "ra", "haka", "manuhiri", "hui",
       "tangihanga", "koha", "maunga", "wai", "kia ora",
       "meri kirihimete", "takurua", "morena", "whanau", "whutuporo",
       "heihei", "hiamoe", "aotearoa"]

print("Welcome to Te Reo Maori Quiz!!!\n")
print("Answer the questions with single Maori Words.(Answers have to be in SMALL CAPS)\n")
x=0    `to store correct answers`
i=0
while i<5 :
    d=random.randint(0,19)
    user_answer = input(questions[d])
    if user_answer.lower() == answers[d] :
        print("Correct Answer!")
        x=x+1
    else :
        print("Incorrect Answer. The correct answer is: ",answers[d])
    i=i+1   
percentage = ((x*100)/5)
print("End of Quiz.\n", "Your Final Score is: ", percentage,"%")

Answer 1

为什么不重塑示例算法，为什么不直接使用random模块中的sample()。您可以执行以下操作来获得5个问题和答案：

from random import sample

q = list(zip(questions, answers))
questions = sample(q, 5)

为您提供五个问题答案对的随机列表：

[（''在土炉中烹制的传统毛利人食物：'，'hangi'），
   （“毛利语中的“圣诞快乐”：”，“ meri kirihimete”），
   （“毛利语为“ Mountain”的单词：”，“ maunga”），
   （“毛利语中“鸡”的单词：”，“ heihei”），
   （“毛利语中的“水”是什么：”，“围”）]
