Python 通过多个页面进行网页抓取不会保存每个结果-beautifulsoup

我的问题是，它在页面间循环，但它不会在我的列表中写入任何内容

最后我打印

len（title）

，它仍然是0

from bs4 import BeautifulSoup
import requests

for page in range(20, 200, 20):
    current_page = 'https://auto.bazos.sk/{}/?hledat=kolesa&hlokalita=&humkreis=&cen'.format(page)
    web_req = requests.get(current_page).text
    soup = BeautifulSoup(requests.get(current_page).content, 'html.parser')

    title_data = soup.select('.nadpis')
    title = []
    for each_title in title_data:
        title.append(each_title.text)
    print(current_page)

print(len(title))

---

将

标题

移出

循环

，您就拥有了它

import requests
from bs4 import BeautifulSoup

title = []
for page in range(20, 40, 20):
    current_page = 'https://auto.bazos.sk/{}/?hledat=kolesa&hlokalita=&humkreis=&cen'.format(page)
    soup = BeautifulSoup(requests.get(current_page).content, 'html.parser')
    title_data = soup.select('.nadpis')
    for each_title in title_data:
        title.append(each_title.text)
    print(current_page)
print(title)

输出：

打印每个_title.text时会发生什么？如果这是预期的文本内容，则.append方法可能有问题。如果没有，请尝试打印其来源等，以找到根本原因非常感谢！完美
