上面的脚本按预期工作，但我想抓取每个产品的信息upc，product type 例如获取这些单页 https://books.toscrape.com/catalogue/a-light-in-the-attic_1000/index 的信息。 html to scrapeupc等product type...所有其他信息都在产品信息中

您可以使用start=URL 中的参数来获取下一页：

import requests
from bs4 import BeautifulSoup

for page in range(0, 10):  # <-- increase number of pages here
    r = requests.get(
        "https://pk.indeed.com/jobs?q=&l=Lahore&start={}".format(page * 10)
    )
    soup = BeautifulSoup(r.content, "html.parser")
    title = soup.find_all("h2", class_="jobTitle")

    for i in title:
        print(i.text)
