属性错误：'list‘对象没有'string’属性

Question

这是我的类所在的文件

#8/23/2020
#Class file

class Questions:
    def __init__(self, prompt, answer):
        self.prompt = prompt
        self.answer = answer

这是与属性错误一起运行的正文

我是新手编码，这个项目是一个多项选择测验项目。我遵循了Mike Dane的教程，并试图使其动态化，但出现了错误。请使用初学者友好的语言

Answer 1

首先，answer == questions.answer是错误的，因为questions (带有s)是一个问题列表，而不是一个问题。它应该是answer == question.answer (不带s)。

其次，当问题只是给出答案而不是真正问你问题时，我不确定这个测验会有多难：

answer = input(questions.answer)

我认为您可能希望传入question.prompt :-)

Answer 2

run_test中有一些问题。下面的代码应该可以修复它们：

def run_test(questions): #This is my function to run the quiz
    score = 0
    for question in questions:
        answer = input(question.prompt)
        if answer == question.answer:
            score += 1
    print("You scored " + str(score) + "/" + str(len(questions)))
run_test(questions)

更改：

1. input(questions.answer) question.answer
2. len(questions.prompts) -> input(question.prompt)注意这里有2处更改-> -> str(len(questions))注意这里有2处更改
