我正在尝试从汤中获取“数据值”,但它们都位于巨大的列表中,并且没有按照网站上显示的格式在不同的列表/列中显示。
我知道标题在这里:
<th class="num record drop-3" data-tsorter="data-val">
<span class="long-points">
proj. pts.
</span>
<span class="short-points">
pts.
</span>
</th>
<th class="pct" data-tsorter="data-val">
<span class="full-relegated">
relegated
</span>
<span class="small-relegated">
rel.
</span>
</th>
<th class="pct" data-tsorter="data-val">
<span class="full-champ">
qualify for UCL
</span>
<span class="small-champ">
make UCL
</span>
</th>
<th class="pct sorted" data-tsorter="data-val">
<span class="drop-1">
win Premier League
</span>
<span class="small-league">
win league
</span>
</th>
这是我正在尝试的:
url = 'https://projects.fivethirtyeight.com/soccer-predictions/premier-league/'
r = requests.get(url = url)
soup = BeautifulSoup(r.text, "html.parser")
table = soup.find("table", {"class":"forecast-table"})
#print(table.prettify())
for i in table.find_all("td", {"class":"pct"}):
print(i)
所以理想情况下,我希望有4个列表,其中包含类名,然后是匹配值
答案 0 :(得分:2)
不确定要使用什么特定的列,但这会获得标记属性中带有data-val
的所有列。
import requests
from bs4 import BeautifulSoup
url = 'https://projects.fivethirtyeight.com/soccer-predictions/premier-league/'
r = requests.get(url)
soup = BeautifulSoup(r.text, "html.parser")
table = soup.find("table", {"class": "forecast-table"})
team_rows = table.find_all("tr", {"class": "team-row"})
for team in team_rows:
print("Team name: {}".format(team['data-str']))
team_data = team.find_all("td")
for data in team_data:
if hasattr(data, 'attrs') and 'data-val' in data.attrs:
print("\t{}".format(data.attrs['data-val']))
print("\n")
如果我确实正确理解了您的问题,则说明您正在寻找最后两个值,这些值在html源代码中未加标签。在这种情况下,您可以尝试简单地寻找tag[6]
,尽管它当然不是很健壮-但是此是 html解析,因此“不是很健壮”是针对课程恕我直言的。
我在这里要做的是查找所有团队行(由于类名,这很容易),然后简单地遍历团队行的{{1}中的所有td
标签}。
