catch specific HTTP error in python

Question

I want to catch a specific http error and not any one of the entire family.. what I was trying to do is --

import urllib2
try:
   urllib2.urlopen(\"some url\         


        

Answer 1

Python 3

from urllib.error import HTTPError

Python 2

from urllib2 import HTTPError

Just catch HTTPError, handle it, and if it's not Error 404, simply use raise to re-raise the exception.

See the Python tutorial.

e.g. complete example for Pyhton 2

import urllib2
from urllib2 import HTTPError
try:
   urllib2.urlopen("some url")
except HTTPError as err:
   if err.code == 404:
       
   else:
       raise
