URL = r'https://data.ipu.org/women-ranking?month=12&year=2019'
Res = requests.get(URL)
soup = BeautifulSoup(Res.text , 'lxml')
ul = soup.find('ul',{'class' : 'exports'})
li = ul.find('li')
for i , link in enumerate(li , start =1):
try:
link = item.find("a" )
link = link.get("href")
except:
pass
print(link)
links.append(link)
我收到以下错误消息：'NoneType' object is not iterable
我想抓取所有位于li标记下的href网址
