如何拉取特定的 "data-stat" 值？ (python)

Question

到目前为止，代码从 https://www.basketball-reference.com 中拉出一个页面，并使用数据统计 class(???).[=15= 获取 tr_body 中的任何数据]

我需要一种方法来提取数据统计的特定值，例如 https://www.basketball-reference.com/players/l/lowryky01.html data-stat="pos" = PG 的输出。

from bs4 import BeautifulSoup
import requests

first = ()
first_slice = ()
last = ()


def askname():
    global first
    first = input(str("First Name of Player?"))
    global last
    last = input(str("Last Name of Player?"))
    print("Confirmed, loading up " + first + " " + last)
# asks user for player name

askname()


first_slice_result = (first[:2])
last_slice_result = (last[:5])
print(first_slice_result)
print(last_slice_result)
# slices player's name so it can match the format bref uses
first_slice_resultA = str(first_slice_result)
last_slice_resultA = str(last_slice_result)

first_last_slice = last_slice_resultA + first_slice_resultA

lower = first_last_slice.lower() + "01"

start_letter = (last[:1])
lower_letter = (start_letter.lower())
# grabs the letter bref uses for organization

print(lower)
source = requests.get('https://www.basketball-reference.com/players/' + lower_letter + '/' + lower + '.html').text

soup = BeautifulSoup(source, 'lxml')
tbody = soup.find('tbody')
pergame = tbody.find(class_="full_table")
classrite = pergame.find(class_="right")
tr_body = tbody.find_all('tr')
print(pergame)


# seperates data-stat, apparently you can use .get to get obscure classes
for trb in tr_body:
    print(trb.get('id'))

    th = trb.find('th')
    print(th.get_text())
    print(th.get('data-stat'))


    for td in trb.find_all('td'):
        print(td.get_text())
        print(td.get('data-stat'))

大约 4 个月前开始这个项目，我很难记住如何拆分和提取特定的数据统计信息。

嗯，据我所知，你基本上已经完成了你想要的。

从这一点开始，只需将您提取的信息组织到字典中，然后您就可以通过它们的键提取值。

for trb in tr_body:
    print(trb.get('id'))

    th = trb.find('th')
    print(th.get_text())
    print(th.get('data-stat'))
    
    row = {}
    for td in trb.find_all('td'):
        row[td.get('data-stat')] = td.get_text()
    
    print(row['pos'], row['team_id'], row['fg_pct'])

希望对您有所帮助。
