import requests

from requests.exceptions import RequestException

def get_one_page(url):
try:
r = requests.get(url)
if r.status_code == 200:
r.encoding = "utf-8" # 防止乱码
return r.text
return None
except RequestException:
return None

def parse_html(html):
global i
pattern = re.compile(r'<li.?class="gl-item">.?<a.?<img.*?source-data-lazy-img="(.*?)" />.?'
r'.?

for i in img:
  print(i[1])  # 价格
print(i[3] + i[4] + i[5])  # name
print(i[6], i[7])  # author
print(i[8])  # store
print(i[9], i[10])
print()

print(i[3] + i[4] + i[5]) # name这里要缩进
