python 활용 웹 사이트가 존재하는지 체크 :

Python check if website exists

You can use HEAD request instead of GET. It will only download the header, but not the content. Then you can check the response status from the headers.

import httplib
c = httplib.HTTPConnection('www.example.com')
c.request("HEAD", '')
if c.getresponse().status == 200:
   print('web site exists')

or you can use urllib2

import urllib2
try:
    urllib2.urlopen('http://www.example.com/some_page')
except urllib2.HTTPError, e:
    print(e.code)
except urllib2.URLError, e:
    print(e.args)

or you can use requests

import requests
request = requests.get('http://www.example.com')
if request.status_code == 200:
    print('Web site exists')
else:
    print('Web site does not exist')
