python - 与 BeautifulSoup 中的 HTML 变量交互

问题描述

我编写了从特定 URL 获取酒店名称和来自 bookings.com 的价格的代码。我试图让该工具仅输出我正在寻找的一家酒店的名称和价格。我可以在页面上输出所有酒店的名称和价格，但是当我运行一个 IF 语句来尝试输出一个单数时它不起作用。我尝试将 Str() 放在选择酒店名称和价格的代码周围，但这不会导致任何输出。当前代码仅返回“错误酒店”。一旦被刮掉，我是否无法操纵变量？因为我也想比较酒店的价格。

from bs4 import BeautifulSoup
import requests

headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.128 Safari/537.36'}

解决方案

刮后有两个空格hotelname，一个前导空格字符和一个尾随空格字符。用于strip()消除hotelname.

hotelname = hotelname.strip()
