如何将完整列表合并到数据框中。当我打印时，它似乎只打印第一条记录，它还包括 \n 和其他冗余，如 ' 等。

    import requests
    from requests_html import HTML, HTMLSession
    from bs4 import BeautifulSoup
    import pandas as pd
    import csv
    import json

    url = 'https://lehighsports.com/sports/mens-soccer/schedule/2018'
    lehigh = requests.get(url).text
    soup = BeautifulSoup(lehigh,'lxml')

    for opp in soup.find_all('div',class_="sidearm-schedule-game-opponent-text"):
        opp_list = []
        opp_list.append(opp.text)
     #   print(opp_list)

    for conf in soup.find_all('div',class_="sidearm-schedule-game-conference-conference"):
        conf_list = []
        conf_list.append(conf.text)
    #    print(conf_list)

    dict = {'opponent':[opp_list],'conference':[conf_list]}
    df = pd.DataFrame(dict)
    print(df)

【解决方案1】：

您在每次迭代中将 opp_list 和 conf_list 设置为 [] - 仅将它们初始化一次。另外，您不必在创建字典时放入括号{'opponent':opp_list,'conference':conf_list}

要删除空格，您可以使用带有strip=True 和separator= 参数的.get_text() 方法。

例如：

import requests
import pandas as pd
from bs4 import BeautifulSoup

url = 'https://lehighsports.com/sports/mens-soccer/schedule/2018'
lehigh = requests.get(url).text
soup = BeautifulSoup(lehigh,'lxml')

opp_list = []
for opp in soup.find_all('div',class_="sidearm-schedule-game-opponent-text"):
    opp_list.append(opp.get_text(strip=True, separator=' '))

conf_list = []
for conf in soup.find_all('div',class_="sidearm-schedule-game-conference-conference"):
    conf_list.append(conf.get_text(strip=True))

dict = {'opponent':opp_list,'conference':conf_list}
df = pd.DataFrame(dict)
print(df)

打印：
