If condition on error message after response.read

response = urllib2.urlopen("http://example.com/Hi")
html = response.read()

Is it possible that when the above code is run while the Hi directory has been removed (or the server is not available), instead of crashing, an action like below is done?

if html==404:
    print("No response")

Solution

You can use the requests module
simply after getting the request, check the status code

    import requests
    r = requests.get('http://httpbin.org/status/404')
    print(r.status_code) # the output is the int: 404

if everything is ok

if r.ok:
    # cool stuff :)

if page not found:

if r.status_code == 404:
    # so sad :(
