改进代码：
import requests
import os
import redef get_html_data(url):headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"}response = requests.get(url=url,headers=headers)response.encoding = response.apparent_encodingreturn responsedef get_analyse_html(response):href_list = re.findall("<td width='52%' height='23'><a href=\"(.*?)\" class=\"title\" target='_blank'>",response.text)title_list = re.findall("class=\"title\" target='_blank'>(.*?)</a>", response.text)return title_list,href_listdef save(title_list,doc_list):filename = '试卷\\'if not os.path.exists(filename):os.mkdir(filename)for title,doc in zip(title_list,doc_list):with open('试卷\\' + title + '.rar', mode='wb') as f:f.write(doc)print(f'{title}已经下载完成')def get_doc(href_list):doc_list = []for href in href_list:href = 'https://www.shijuan1.com' + hrefdoc_html = get_html_data(href)data_url = 'https://www.shijuan1.com' + re.findall('<li><a href="(.*?)" target="_blank">本地下载</a></li>', doc_html.text)[0]doc = get_html_data(data_url).contentdoc_list.append(doc)return doc_listif __name__ == '__main__':url = 'https://www.shijuan1.com/a/sjsxg3/list_727_1.html'response = get_html_data(url)title_list,href_list = get_analyse_html(response)doc_list = get_doc(href_list)save(title_list,doc_list)进一步写成类：
import requests
import os
import re
class save_doc():def get_html_data(self,href):headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"}response = requests.get(url=href, headers=headers)response.encoding = response.apparent_encodingreturn responsedef get_analyse_html(self,response):href_list = re.findall("<td width='52%' height='23'><a href=\"(.*?)\" class=\"title\" target='_blank'>",response.text)title_list = re.findall("class=\"title\" target='_blank'>(.*?)</a>", response.text)return title_list, href_listdef save(self,title_list,doc_list):filename = '试卷\\'if not os.path.exists(filename):os.mkdir(filename)for title, doc in zip(title_list, doc_list):with open('试卷\\' + title + '.rar', mode='wb') as f:f.write(doc)print(f'{title}已经下载完成')def get_doc(self,href_list):doc_list = []for href in href_list:href = 'https://www.shijuan1.com' + hrefdoc_html = self.get_html_data(href)data_url = 'https://www.shijuan1.com' + re.findall('<li><a href="(.*?)" target="_blank">本地下载</a></li>', doc_html.text)[0]doc = self.get_html_data(data_url).contentdoc_list.append(doc)return doc_list
save = save_doc()
response = save.get_html_data('https://www.shijuan1.com/a/sjsxg3/list_727_1.html')
title_list,href_list = save.get_analyse_html(response)
doc_list = save.get_doc(href_list)
save.save(title_list,doc_list)对于类还是很不熟，我想要类中的方法返回的值，可以直接传入类中的其他方法，应该怎么写呢？我想要写一个类，传入一个url,直接下载所需要的数据，即最终代码为
save = save_doc("https://www.shijuan1.com/a/sjsxg3/list_727_1.html")不需要上面那么复杂的传来传去，应该怎么做呢？
