Python 跳过BeautifulSoup中的空行

我目前正在尝试使用BeautifulSoup从1001TrackList（一个在DJ混音中列出曲目的网站）中收集数据

如果混音中的曲目没有ID，1001TrackLists会将其保留为数据表上的“ID-ID”，该数据表在已删除的代码中显示为空白条目，并将我的for循环弄乱

如何让Python跳过曲目列表中的“空白”ID，并在空白ID之后继续抓取数据

到目前为止，我的代码是：

headers = {'User-Agent': 'Chrome/51.0.2704.103'}
page_link  = 'https://www.1001tracklists.com/tracklist/7mzt0y9/boddika-joy-orbison-rinse-fm-hessle-audio-cover-show-2014-01-16.html'
page_response = requests.get(page_link, headers=headers)
soup = bs(page_response.content, "html.parser")

tracknumbers = []
tracknames = []
artistnames = []
mixnames = []
dates = []


tracknames_scrape = soup.find_all("div", class_="tlToogleData", div=True)
artistnames_scrape = soup.find_all("meta", itemprop="byArtist")

for (i, track) in enumerate(tracknames_scrape):
    tracknumbers.append(i+1)
    trackname = track.meta['content']
    tracknames.append(trackname)
    print(str(i+1) + str(". ") + trackname)

目前，我能够返回所有曲目，直到我点击一个空白条目，之后我会出现以下错误：

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-9-de6ecd3caa59> in <module>
      1 for (i, track) in enumerate(tracknames_scrape):
      2     tracknumbers.append(i+1)
----> 3     trackname = track.meta['content']

TypeError: 'NoneType' object is not subscriptable

---------------------------------------------------------------------------
TypeError回溯（最近一次调用上次）
在里面
枚举（tracknames\u scrap）中的（i，track）为1：
2个轨号。追加（i+1）
---->3 trackname=track.meta['content']
TypeError:“非类型”对象不可下标

---

如果我使用一个没有空白曲目ID的URL，脚本就可以完美地工作。

使用下面的css选择器获取曲目名称

import requests
from bs4 import BeautifulSoup as bs
headers = {'User-Agent': 'Chrome/51.0.2704.103'}
page_link  = 'https://www.1001tracklists.com/tracklist/7mzt0y9/boddika-joy-orbison-rinse-fm-hessle-audio-cover-show-2014-01-16.html'
page_response = requests.get(page_link, headers=headers)
soup = bs(page_response.content, "html.parser")

tracknumbers = []
tracknames = []
artistnames = []
mixnames = []
dates = []


tracknames_scrape =soup.select('div[itemprop="tracks"]>[itemprop="name"]')
#artistnames_scrape = soup.find_all("meta", itemprop="byArtist")

for (i, track) in enumerate(tracknames_scrape):
    tracknumbers.append(i+1)
    trackname = track['content']
    tracknames.append(trackname)
    print(str(i+1) + str(". ") + trackname)

我排除了我的导入，但是是的，除此之外，这里的所有内容都以isCan运行。您可以发布堆栈跟踪以显示代码失败的位置。只需在except子句中添加一个try expect with continue，该子句围绕

trackname=track.meta['content']

。或者，您可以在尝试访问之前检查曲目的类型，例如

如果track.meta不是None

在处理信息之前添加测试。类似于

if track.meta:

。您能发布所需输出的示例吗？我排除了我的导入，但是的，除此之外，这里的所有内容都在运行。您可以发布堆栈跟踪以显示代码失败的位置只需在
