我正在用Pandas队和美女队刮足球花名册，但它刮不到两列

Question

这是我的密码：

from bs4 import BeautifulSoup as bs
import requests
import pandas as pd

r = requests.get('https://rolltide.com/roster.aspx?roster=226&path=football', headers = {'User-Agent':'Mozilla/5.0'})
soup = bs(r.content, 'lxml')
results = {}

for num, p in enumerate(soup.select('.sidearm-roster-player')):
    results[num] = {'position': p.select_one('.sidearm-roster-player-position >span:first-child').text.strip()
           ,'Height': p.select_one('.sidearm-roster-player-height').text
           ,'Weight': p.select_one('.sidearm-roster-player-weight').text
           ,'Number': p.select_one('.sidearm-roster-player-jersey-number').text
           ,'Name': p.select_one('.sidearm-roster-player-name a').text
           ,'Year': p.select_one('.sidearm-roster-player-academic-year').text
           ,'Hometown': p.select_one('.sidearm-roster-player-hometown').text
           ,'Highschool': p.select_one('.sidearm-roster-player-highschool').text
          }
df = pd.DataFrame(results.values(), columns = ['Number','Name','Position','Height','Year','Hometown','Highschool'])
df.to_excel(r'desktop\Alabama.xlsx', index=False)

除了“数字”和“位置”我不知道为什么。知道怎么回事吗

Answer 1

对于您有结果的数字，只需替换：

,'Number': p.select_one('.sidearm-roster-player-jersey-number').text

与

,'Number': p.select_one('.sidearm-roster-player-jersey-number').text.strip()

对于这个职位来说，这是因为你的写作方式与你的写作方式不符。 更改：

'position': p.select_one('.sidearm-roster-player-position >span:first-child').text.strip()

至

'Position': p.select_one('.sidearm-roster-player-position >span:first-child').text.strip()

Answer 2

您可以使用pandas内置的read\u html函数：

df = pd.read_html('https://rolltide.com/sports/football/roster/2019')[2] #one you're after is the 3rd table being scraped

结果：
