c:/
#coding:utf-8
import urllib
import re
import os
exchange=['NASDAQ','NYSE','AMEX']
for down in exchange:
    myfile=open('c:/'+down,'w')
    url='
http://www.nasdaq.com/screening/companies-by-industry.aspx?exchange='+down+'&render=download
'
    file=urllib.urlopen(url).read()
    myfile.write(file)
    print 'ok',down
    myfile.close()
