Question

我正在尝试将表行中的所有数据放入一个列表中，但是其中一些是表头，有些是表数据，不确定如何同时获取它们。

这是使用bs4的Python 3.7

import requests, bs4

url = 'https://www.basketball-reference.com/players/a/abrinal01.html'
res = requests.get(url)
res.raise_for_status()

soup = bs4.BeautifulSoup(res.text, 'html.parser')
elems = soup.select('#per_game')

table = soup.find("table", { "id" : "per_game" })
table_rows = table.find_all('tr')

for tr in table_rows:
    td = tr.find_all('td')
    row = [i.text for i in td]
    print(row)

我可以将所有表数据放入一个列表中，因此第一列的所有内容都正确，但第一列本身的数据不正确。

要在数据中包含标题，可以将find_all('td')和find_all('th')的输出合并。这就是你想要的吗？

import requests, bs4

url = 'https://www.basketball-reference.com/players/a/abrinal01.html'
res = requests.get(url)
res.raise_for_status()

soup = bs4.BeautifulSoup(res.text, 'html.parser')
elems = soup.select('#per_game')

table = soup.find("table", { "id" : "per_game" })
table_rows = table.find_all('tr')

for tr in table_rows:
    td = tr.find_all('th') + tr.find_all('td')
    row = [i.text for i in td]
    print(row)

产生此输出：

['Season', 'Age', 'Tm', 'Lg', 'Pos', 'G', 'GS', 'MP', 'FG', 'FGA', 'FG%', '3P', '3PA', '3P%', '2P', '2PA', '2P%', 'eFG%', 'FT', 'FTA', 'FT%', 'ORB', 'DRB', 'TRB', 'AST', 'STL', 'BLK', 'TOV', 'PF', 'PTS']

['Career', '', '', 'NBA', '', '174', '16', '16.0', '1.8', '4.5', '.387', '1.3', '3.4', '.368', '0.5', '1.1', '.443', '.525', '0.5', '0.6', '.880', '0.3', '1.1', '1.4', '0.5', '0.5', '0.1', '0.4', '1.7', '5.3']
