在HTML的以下示例部分中，我使用beautifilsoup（简单易用）从页面上提取了很多足球得分：
<tr class='report' id='match-row-EFBO695086'> <td class='statistics show' title='Show latest match stats'> <button>Show</button> </td> <td class='match-competition'> Premier League </td> <td class='match-details
teams'> <p> <span class='team-home teams'> <a href='/sport/football/teams/manchester-city'>Man City</a> </span> <span class='score'> <abbr title='Score'> 1-0 </abbr> </span> <span class='team-away teams'> <a
href='/sport/football/teams/crystal-palace'>Crystal Palace</a> </span> </p> </td> <td class="match-date"> Sat 28 Dec </td> <td class='time'> Full time </td> <td class='status'> <a class='report'
href='/sport/football/25474625'>Report</a>
from bs4 import BeautifulSoup
import urllib.request
import csv
url = 'http://www.bbc.co.uk/sport/football/teams/manchester-city/results/'
page = urllib.request.urlopen(url)
soup = BeautifulSoup(page)
for score in soup.findAll('abbr'):
print(score.string)

0-2
1-1
如何从HTML的此部分提取团队名称：
<span class='team-away teams'> <a href='/sport/football/teams/crystal-palace'>Crystal Palace</a> </span>
想法是首先获取包含有关每个游戏的信息的元素-这些是tr带有的标签class="report"。对于每一行，请按班级获取团队名称，team-home并按team-away标签名称得分abbr：
from bs4 import BeautifulSoup
import urllib.request
url = 'http://www.bbc.co.uk/sport/football/teams/manchester-city/results/'
page = urllib.request.urlopen(url)
soup = BeautifulSoup(page)
for match in soup.select('table.table-stats tr.report'):
team1 = match.find('span', class_='team-home')
team2 = match.find('span', class_='team-away')
score = match.abbr
if not all((team1, team2, score)):
continue
print(team1.text, score.text, team2.text)
印刷：
Man City 1-2 CSKA
Man City 1-0 Man Utd
Man City 0-2 Newcastle
West Ham 2-1 Man City
...
仅供参考，table.table-stats tr.report是一个CSS选择器，所有匹配tr的标签与class="report"内部table用class="table-stats"。
