import requests
import re
url = "http://zuimeia.com"
r = requests.get('http://zuimeia.com/community/app/hot/?platform=2')
pattern = re.compile(r'<a class="community-app-cover-wrapper" href="(.*?)" target="_blank">')
urlList = pattern.findall(r.content)

def requestsUrl(url):
 r = requests.get(url)
 title = re.findall(r'"app-title"><h1>(.*?)</h1>',r.content)
 #print title
 category = re.findall(r'<a class="app-tag" href="/community/app/category/title/.*?/?platform=2">(.*?)</a>',r.content)
 #print category

 describe = re.findall(r'<div id="article_content">(.*?)<div class="community-image-wrapper">',r.content)
 #print type(describe[0])
 strdescribe = srtReplace(describe[0])
 #print strdescribe

 downloadUrl = re.findall(r'<a class="download-button direct hidden" href="(.*?)"',r.content)

     '</h6>', '</h7>','</strong>','<b>', '</b>']
 for eachListReplace in listReplace:
