res.encoding="utf-8"

soup =BeautifulSoup(res.text,"html.parser")

#print(soup.prettify())

 

import csv

with open('C:/xxx.csv', 'w', newline='') ascsvfile:

                            quotechar='|', quoting=csv.QUOTE_MINIMAL)

   spamwriter.writerow(['id','url','总排名','分类排名','app名称','公司'])

   for link in soup.find_all('div',class_="thumbnail"):

       total='-'

       if(len(link.h6.next_sibling.next_sibling)>1):

           total=link.h6.next_sibling.next_sibling.contents[1].text

       id=link.a['href'].split('/')[4]

       url='https://aso100.com'+ link.a['href']

       

       spamwriter.writerow([id,url,total,''.join(link.a.h5.text.split('.')[0:1]),''.join(link.a.h5.text.split('.')[1:2]),link.a.h6.text])
