用漂亮汤Python打印带有文本的类名

Question

我想打印带有所有选项的类名。对于错误的答案，它只是radio-button-click-target，但是有了正确的选项，它的单选按钮-点击-目标更正问题。

import requests
from bs4 import BeautifulSoup
addresses = ['https://www.ilmkidunya.com/online-test/5th-class-science-english-meduim-mcqs-with-answers?startfrom=0&last=92']
subjects = ['05th-Science-EM-']
for runscript in range(0, len(addresses)):
    response = requests.get(addresses[runscript])
    soup = BeautifulSoup(response.text, 'lxml')
    ques_id = soup.find_all('div', class_='q-title')
    ques_det = soup.find_all('div', class_='q-desc')
    optn_det = soup.find_all('div', class_='choose-answer-block')
    for i in range(0, len(ques_id)):
        unformated_ques_id = (ques_id[i].text)
        formated_ques_id = unformated_ques_id.replace("Question #  ", subjects[runscript])
        print(formated_ques_id)
        #print('\n')
        print(str(ques_det[i].text).strip())
        #print('\n')
        options = optn_det[i].find_all('label', class_='radio-button-click-target')
        for opn in options:
            print(str(opn.text).strip())
            #print('\n')
        print('<----->')

Answer 1

按以下方式更改选择器，并删除对已经字符串的str调用。此外，在适当的情况下，使用' class‘提取类，我使用join组合多值类：

import requests
from bs4 import BeautifulSoup

addresses = ['https://www.ilmkidunya.com/online-test/5th-class-science-english-meduim-mcqs-with-answers?startfrom=0&last=92']
subjects = ['05th-Science-EM-']

with requests.Session() as s:
    for runscript in range(0, len(addresses)):
        response = s.get(addresses[runscript])
        soup = BeautifulSoup(response.text, 'lxml')
        ques_id = soup.find_all('div', class_='q-title')
        ques_det = soup.find_all('div', class_='q-desc')
        optn_det = soup.find_all('div', class_='choose-answer-block')

        for i in range(0, len(ques_id)):
            unformated_ques_id = (ques_id[i].text)
            formated_ques_id = unformated_ques_id.replace("Question #  ", subjects[runscript])
            print(formated_ques_id)
            print(ques_det[i].text.strip())
            options = optn_det[i].select('label.radio-button-click-target')

            for opn in options:
                print(' '.join(opn['class']), opn.text.strip())
            print('<----->')

Answer 2

你应该再试一试。

for opn in options:
            print(' '.join(opn['class']), end=' : ')
            print(str(opn.text).strip())

这将得到你想要的结果。

Answer 3

实际上，您的代码包含多个错误：

1. 您不需要多次调用soup对象！因为你可以拿起你的goal，然后解析它。
2. ，如果你可以使用一个函数，你不需要使用两个函数。实际上，像.text.strip()这样的东西可以通过.text.strip()一次处理很多错误，但只需转到我的代码中，您就可以完全了解

了。

from bs4 import BeautifulSoup
import requests


def main(url):
    r = requests.get(url)
    soup = BeautifulSoup(r.text, 'lxml')
    goal = soup.select_one('#divQuestion1')

    title = goal.select_one('.q-desc').get_text(strip=True)
    can = goal.select_one(
        'label[class$=correctquestions]').get_text(strip=True)
    wan = [x.get_text(strip=True)
           for x in goal.select('label[class$=click-target]')]
    print("Question: {}\nCorrect-Answer: {}\nWrong-Answers: {}".format(title, can, wan))


main('https://www.ilmkidunya.com/online-test/5th-class-science-english-meduim-mcqs-with-answers?startfrom=0&last=92')
