我只想打印给定数据的 10 个结果。我拥有的数据超过 10

Question

import requests

from bs4 import BeautifulSoup

webpage = requests.get("https://www.spinneyslebanon.com/catalogsearch/result/?q=pepsi")

soup = BeautifulSoup(webpage.content, 'html.parser')

title = soup.find_all('a', 'product-item-link')
price = soup.find_all('span', class_='price')

for t, p in zip(title, price):

   print("{:<60} {:<30}".format(t.get_text(strip=True), p.get_text(strip=True)))

Answer 1

您应该可以使用 enumerate 作为计数器以在正确的数字处停止：

for index,tp in enumerate(zip(title, price)):
    if index >= 10:
        break
    t, p = tp
    print("{:<60} {:<30}".format(t.get_text(strip=True), p.get_text(strip=True)))

Answer 2

您可以 return 前 10 个价格和标题是这样的。

title = soup.find_all('a', 'product-item-link')[:10]
price = soup.find_all('span', class_='price')[:10]

Answer 3

您可以使用这种方式获得前 10 个结果。只需在代码中的 for 循环之前添加这一行。

title, price = title[0:10], price[0:10]
