nba 结合网络解析：'NoneType' 对象没有属性 'find_all'

Question

嗯，我想要 table 播放器和信息，但我运行遇到了一个我不明白的问题。

问题出在第8-9行； trs = table.find_all('tr')

from bs4 import BeautifulSoup
import requests

   url = 'https://www.nbadraft.net/2019-nba-draft-combine-measurements'
   resp = requests.get(url)
   soup = BeautifulSoup(resp.content, 'html.parser')
   table = soup.find('div', attrs={'class':'content'}).tbody
   trs = table.find_all('tr')

   for tr in trs:
    tds = tr.find_all('td')
    row = [td.text for td in tds]

---预期--

[['player','info','info',等等]]

---实际---

trs = table.find_all('tr') AttributeError: 'NoneType' 对象没有属性 'find_all'

Answer 1

问题是您首先选择了 <tbody>，这只是一个 header。所有<tr>在下<tbody>。此脚本选择所有行并打印它们。

from bs4 import BeautifulSoup
import requests

url = 'https://www.nbadraft.net/2019-nba-draft-combine-measurements'
resp = requests.get(url)
soup = BeautifulSoup(resp.content, 'lxml')

rows = []
for tr in soup.select('.content table tr'):
    tds = tr.find_all('td')
    rows.append([td.text.strip() for td in tds])

for row in rows:
    print(''.join( '{: <22}'.format(t) for t in row ))

打印：
