Получить информацию, используя трудности с BeautifulSoup

/ 28 апреля 2018

Я новичок в Beautifulsoup, я хотел бы получить определенный элемент внутри тега th, но проблема в том, что нет способа идентифицировать теги.

Ниже приведены элементы HTML 

<div class="tbl_racing_head" >
		<table class="tblgrey">
			<thead>
			<tr>
			  <th width="65%" class="aln_left"><a name="1"></a>Race 1. THE ZILLAH CUP.<span class="pull-right"><a href="/index.php/en/racing/results?view=full#top" id="back-top">Back to Top</a></span></th>
			  <th width="10%">1365 m</th>
			  <th width="15%">Rating 25-0</th>
			  <th width="10%">12h45</th>
			</tr>
			</thead>
		</table>
		</div>

Я хочу получить th, который имеет значение 1365, но я не могу найти способ получить значение. Я предполагаю, что я должен использовать nextsibling или какой-либо родительский метод, но у меня возникают трудности. Ниже приведен код, который я пробовал 

url = 'http://www.mauritiusturfclub.com/index.php/en/racing/results? 
   meeting='+str(race_played)+'-'+str(2012)+'&view=full'
   source_code = requests.get(url)
   plain_text = source_code.text
   soup = BeautifulSoup(plain_text,'html.parser')
   print('Track '+soup.findAll('th',{'width':'10%'})[3])

Я получаю ошибки, которые, похоже, не работают, может кто-нибудь объяснить мне, что происходит? спасибо 

<div class="tbl_racing_head" >
		<table class="tblgrey">
			<thead>
			<tr>
			  <th width="65%" class="aln_left"><a name="1"></a>Race 1. THE ZILLAH CUP.<span class="pull-right"><a href="/index.php/en/racing/results?view=full#top" id="back-top">Back to Top</a></span></th>
			  <th width="10%">1365 m</th>
			  <th width="15%">Rating 25-0</th>
			  <th width="10%">12h45</th>

Попробуйте 

s = """<div class="tbl_racing_head" >
        <table class="tblgrey">
            <thead>
            <tr>
              <th width="65%" class="aln_left"><a name="1"></a>Race 1. THE ZILLAH CUP.<span class="pull-right"><a href="/index.php/en/racing/results?view=full#top" id="back-top">Back to Top</a></span></th>
              <th width="10%">1365 m</th>
              <th width="15%">Rating 25-0</th>
              <th width="10%">12h45</th>
            </tr>
            </thead>
        </table>
        </div>"""
from bs4 import BeautifulSoup
soup = BeautifulSoup(s,'html.parser')
for tr in soup.findAll("tr"):
    print(tr.find("th", {'width':'10%'}).text)
