import time
from BeautifulSoup import BeautifulSoup
import urllib

mon1=""
mon2=""

urlstr=[]

for i in range(31):

    tmpstr=str(i+1)

    urlstr.append(mon1+tmpstr.zfill(2)+'/')
for i in range(22):

    tmpstr=str(i+1)

    urlstr.append(mon2+tmpstr.zfill(2)+'/')


for eachurl in urlstr:

    sock=urllib.urlopen(eachurl)
    strhtml=sock.read()
    soup=BeautifulSoup(strhtml)
    wealist=soup.find("div","wtday")
    print wealist.text
    time.sleep(1)
