我正在嘗試使用 Python 中的 BeautifulSoup 抓取各種網(wǎng)站。假設(shè)我有以下html摘錄：<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>我需要結(jié)果采用以下格式：District:              AnyState - At LargePolitical Highlights:  AnyTown City Council, 19XX-XXBorn:                  June X, 19XX; AnyTown, Calif.Residence:             Some TownReligion:              EpiscopalianFamily:                Wife, Some Name; two childrenEducation:             Some State College, A.A. 19XX; Some Other State College, B.A. 19XXElected:               19XX但是，到目前為止，我只能實現(xiàn)以下目標(biāo)：District:Political Highlights:Born:Residence:Religion:Family:Education:Elected:使用以下代碼：import urllib.requestimport sysfrom bs4 import BeautifulSoupdef 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])總之，我如何提取District和AnyState - At Large從<span class="sub_heading">District:</span> AnyState - At Large<br/>在作進一步處理列表積累的結(jié)果？
