如何抓取标题? [英] How to webscrape a title?

问题描述

我想知道如何抓取 youtube 播放列表中第一个视频的标题?

I was wondering how to webscrape the title of the first video in an youtube-playlist ?

到目前为止我尝试过的:

what I have so far try'd:

import urllib.request
from bs4 import BeautifulSoup

theurl = "https://www.youtube.com/watch?v=lp-EO5I60KA&list=PLMC9KNkIncKtPzgY-5rmhvj7fax8fdxoj"
thepage = urllib.request.urlopen(theurl)
soup = BeautifulSoup(thepage, "html.parser")

print(soup.findAll("h1",{"class":"title style-scope ytd-video-primary-info-renderer"}))

但它只打印 = "[]" 作为输出.我在这里做错了吗?

But it only prints = "[]" as output. Am I doing something wrong here ?

问候

推荐答案

我做了以下事情:

all = (soup.findAll("span",{"class":"title"}))
for a in all:
    print(a.text)
    break

当我查看汤时，我可以看到播放列表对于列表中的每首歌曲都有class=title.输出为:

When I looked in the soup, I could see the playlist has class=title for each song in the list. The output is:

Ed Sheeran - Thinking Out Loud [Official Video]
