random.choice 在 python 的元组中没有重复项

Question

我正在制作一个简单的翻译游戏，我不想在运行此代码时重复“测验”。

这是我当前提出重复问题的代码：

sentence = ("naranja", "azul", "llamada", "blanco", "negro", "cancion", "rojo", "hielo", "cara")

answer = ("orange", "blue", "call", "white", "black", "sing", "red", "ice", "face")

num = 0

while num <= len(sentence):
    quiz = random.choice(sentence)
    order = sentence.index(quiz)
    print(quiz)
    a = input("Translate in English : ")
    if a == answer[order]:
        print("Correct!")

    else :
        print("Wrong!", answer[order])

Answer 1

干净的方法是尽可能避免操纵索引。

您可以使用zip 获得成对的（问题，答案），然后使用 random.shuffle随机播放此列表，您只需对其进行迭代：

from random import shuffle


sentence = ("naranja", "azul", "llamada", "blanco", "negro", "cancion", "rojo", "hielo", "cara")
answer = ("orange", "blue", "call", "white", "black", "sing", "red", "ice", "face")

associations = list(zip(sentence, answer))
shuffle(associations)

for quiz, answer in associations:
    print(quiz)
    a = input("Translate in English : ")
    if a == answer:
        print("Correct!")
    else :
        print("Wrong!", answer)

Answer 2

尝试使用随机sample function。 这可用于为您提供来自给定列表的 n 个元素的随机列表，而不会重复。 在这里，您可以抽取一个大小与问题长度相同的样本，然后遍历测验问题：

import random

sentence = ("naranja", "azul", "llamada", "blanco", "negro", "cancion", "rojo", "hielo", "cara")

answer = ("orange", "blue", "call", "white", "black", "sing", "red", "ice", "face")

num = 0

# Get a randomly ordered list of the questions
quiz_questions = random.sample(sentence, len(sentence))

# Iterate over the random list
for quiz in quiz_questions:
    order = sentence.index(quiz)
    print(quiz)
    a = input("Translate in English : ")
    if a == answer[order]:
        print("Correct!")

    else :
        print("Wrong!", answer[order])
