python之使用 BeautifulSoup 获取 span 之间的文本

我正在尝试使用 Python 中的 BeautifulSoup 抓取各种网站。假设我有以下 html摘录:

<div class="member_biography"> 
<h3>Biography</h3> 
<span class="sub_heading">District:</span> AnyState - At Large<br/> 
<span class="sub_heading">Political Highlights:</span> AnyTown City Council, 19XX-XX<br/> 
<span class="sub_heading">Born:</span> June X, 19XX; AnyTown, Calif.<br/> 
<span class="sub_heading">Residence:</span> Some Town<br/> 
<span class="sub_heading">Religion:</span> Episcopalian<br/> 
<span class="sub_heading">Family:</span> Wife, Some Name; two children<br/> 
<span class="sub_heading">Education:</span> Some State College, A.A. 19XX; Some Other State College, B.A. 19XX<br/> 
<span class="sub_heading">Elected:</span> 19XX<br/> 
</div> 

我需要以下格式的结果:

District:              AnyState - At Large 
Political Highlights:  AnyTown City Council, 19XX-XX 
Born:                  June X, 19XX; AnyTown, Calif. 
Residence:             Some Town 
Religion:              Episcopalian 
Family:                Wife, Some Name; two children 
Education:             Some State College, A.A. 19XX; Some Other State College, B.A. 19XX 
Elected:               19XX 

但是，到目前为止，我只能实现以下目标:

District: 
Political Highlights: 
Born: 
Residence: 
Religion: 
Family: 
Education: 
Elected: 

使用以下代码:

import urllib.request 
import sys 
from bs4 import BeautifulSoup 
 
def main(url): 
    fp = urllib.request.urlopen(url) 
    site_bytearray = fp.read() 
    fp.close() 
 
    #bs_data = BeautifulSoup(site_str,features="html.parser") 
    bs_data = BeautifulSoup(site_bytearray,'lxml') 
    tmplist = bs_data.find_all('span',{'class':'sub_heading'}) 
    for item in tmplist: 
        print(item.text) 
    sys.exit(0) 
 
if __name__ == "__main__": 
    main(sys.argv[1]) 

简而言之，我如何提取 District和 AnyState - At Large来自 <span class="sub_heading">District:</span> AnyState - At Large<br/>并将结果累积到列表中以供进一步处理？

请您参考如下方法:

将您的打印命令替换为:

Python 3.6+:

print(f'{item.text:<25} {item.next_sibling}')  

Python 3 - 3.5:

print('{:<25} {}'.format(item.text, item.next_sibling)) 

输出:

District:                  AnyState - At Large 
Political Highlights:      AnyTown City Council, 19XX-XX 
Born:                      June X, 19XX; AnyTown, Calif. 
Residence:                 Some Town 
Religion:                  Episcopalian 
Family:                    Wife, Some Name; two children 
Education:                 Some State College, A.A. 19XX; Some Other State College, B.A. 19XX 
Elected:                   19XX
