如何根據從用戶輸入獲得的屬性值打印 class 對象？

Question

import pandas as pd
from operator import attrgetter

class Question(object):
    def __init__(self, Question, task, reference, aAnswer, bAnswer, cAnswer, dAnswer, letterAnswer, Relevance):
        self.Question = Question
        self.task = task
        self.reference = reference
        self.aAnswer = aAnswer
        self.bAnswer = bAnswer
        self.cAnswer = cAnswer
        self.dAnswer = dAnswer
        self.letterAnswer = letterAnswer
        self.Relevance = Relevance

df = pd.read_excel('Test Bank 2021.xlsx')

questions = df.values.tolist()
question_instances = []
for p in questions:
    question_instances.append(Question(*p))

我已經開始了上面的項目，我正在創建一個測試程序。 列出了 object 屬性並且不言自明。 “相關性”屬性引用問題數據庫中的不同測試。

例如，如果我想對某人進行“數學”測試，我只想從“相關性”屬性具有“數學”值的對象中提取。

我試過用谷歌搜索這個，但唯一出現的是如何打印屬性。 但我想要的是根據用戶輸入的值打印對象的其他屬性。

它會像這樣開始：

testName = Input("What test would you like to give? ")
testQuestions = Input("How many questions? ")

在此之后，我想過濾大型（1000 項）“question_instances”列表和 select 基於所選問題數量的隨機問題樣本，僅從所選正確相關性的問題中提取。

這是你想要的？

import random
import pandas as pd

class Question(object):
    def __init__(self, Question, task, reference, aAnswer, bAnswer, cAnswer, dAnswer, letterAnswer, Relevance):
        self.Question = Question
        self.task = task
        self.reference = reference
        self.aAnswer = aAnswer
        self.bAnswer = bAnswer
        self.cAnswer = cAnswer
        self.dAnswer = dAnswer
        self.letterAnswer = letterAnswer
        self.Relevance = Relevance

df = pd.read_excel('Test Bank 2021.xlsx')
questions = df.values.tolist()
question_instances = [Question(*p) for p in questions]

testName = input("What test would you like to give? ")
testQuestions = int(input("How many questions? "))

filtered_questions = [q for q in question_instances if q.Relevance == testName]
selected_questions = random.sample(filtered_questions, testQuestions)

for question in selected_questions:
    print(question.Question)
    print(question.aAnswer)
    print(question.bAnswer)
    print(question.cAnswer)
    print(question.dAnswer)
