Answer 1

您的代码过于复杂，您可以使用 css选择器来查找所需的元素：

from bs4 import BeautifulSoup
import requests


soup = BeautifulSoup(requests.get("http://www.notebookcheck.net/Smartphone-Processors-Benchmark-List.149513.0.html").content)

procs = [a.text for a in soup.select("#sortierbare_tabelle tr td.specs a")]


print(procs)

所有处理器都列在表中，其中 id sortierbare_tabelle，处理器的名称位于 td的中标签内/ em>使用 specs 类。

这给了你：

您可能想要查看一个基本的python教程，因为您在代码中执行的很多操作都过于复杂，比如使用processsorList += [j.text]而不是processsorList.append(j.text)。还有pep8 syle guide

要处理处理器没有链接的位置，只需获取所有tr，看看它们是否匹配任何类，首先查找锚点，如果不存在则只需拉出第一个td.spec：

soup = BeautifulSoup(requests.get("http://www.notebookcheck.net/Smartphone-Processors-Benchmark-List.149513.0.html").content) procs = [] for tr in soup.select("#sortierbare_tabelle tr + tr"): if tr.get("class") in [["smartphone_odd"],["smartphone_even"]]: anc = tr.select_one("td.specs a") procs.append(anc.text if anc else tr.select_one("td.specs").text)
