for dl in soup2.find_all('a',class_="omsc-button omsc-no-custom-hover omsc-size-medium omsc-with-icon omsc-style-flat omsc-text-bright"):

r=requests.get(url,headers=headers)
soup=BeautifulSoup(r.text,'html.parser')
game={}
dizhi=[]

for s in soup.find_all('div',class_="row postLists lists"):
   for j in s.find_all('div',{"class":"col-xxs-6 col-xs-4 col-sm-6 col-md-4 col-lg-3 post-card-wrapper"}):

         game={
            '游戏名':j.find('h2').string,
            '链接':download(str(j.find('a',class_="cover").get('href')))
            }
         print(game)

if __name__ == '__main__':
main()
上面的结果居然游戏地址在上面，反而字典里的链接是NONE值奇怪了，这是哪里不对啊！！！为什么！！
