Question

嗨，我想获取位于 ~~和标签~~下面的一些信息，但是我找不到任何解决方案，因为有人可以对此报废有所了解吗？任何获取这些信息的

这是我的python代码汇入要求导入json 从bs4导入BeautifulSoup

  header = {'User-Agent': 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'}
  
  base_url = "https://www.n11.com/super-firsatlar"
  
  r = requests.get(base_url,headers=header)
  
  if r.status_code == 200:
    soup = BeautifulSoup(r.text, 'html.parser')
    books = soup.find_all('li',attrs={"class":"column"})
    result=[]
    for book in books:
      title=book.find('h3').text
      link=base_url +book.find('a')['href']
      picture = base_url + book.find('img')['src']
      price=book.find('p', {'class': 'del'})
      single ={'title':title,'link':link,'picture':picture,'price':price}
      result.append(single)
      with open('book.json','w', encoding='utf-8') as f:
        json.dump(result,f,indent=4,ensure_ascii=False)
  else:
    print(r.status_code)

这是我的html页面

Answer 1

除非我不理解您的问题，否则它应该像这样做一样简单：

del_data = soup.find_all("del")
ins_data = soup.find_all("ins")

这不是您要实现的目标吗？如果没有，请澄清您的问题

Answer 2

del和ins不是class名称，而是tags。您只需使用Soup.find_all('del')

即可找到它们

price = book.find_all('del')
        for p in price:
            print(p.text)

给予 2.999,00土耳其里拉 189,90 TL TL 8.308,44 499,90 TL 6.999,00土耳其里拉 99,00 TL 18,00 TL 499,00土耳其里拉 169,99土耳其里拉 1.499,90 TL 3.010,00 TL 2.099,90 TL ...... 我想这就是你想要的。您必须在此处访问text属性。因此，该元素已定位。您要序列化的方式是另一个问题。
