kaggle kernels: urllib.request.urlopen not working for any url

What is the best way to handle fetching of list of urls in kaggle kernels?

I tried first testing with google.com.

First Method: Using urllib.request

import urllib.request resp =  urllib.request.urlopen('http://www.google.com')

This lead to error of gai and urlopen error [Errno -2] Name or service not known

Second Method: Using requests

import requests resp = requests.get('http://www.google.com')

This lead to error gaierror: [Errno -3] Temporary failure in name resolution and Failed to establish a new connection: [Errno -3] Temporary failure in name resolution.

import urllib.request
req = urllib.request.Request('http://www.google.com')
print (req)

try:
    response = urllib.request.urlopen(req)
    print (response)
except urllib.error.URLError as e:
    print (e.reason)
    print("something wrong")

Output:

<urllib.request.Request object at 0x7fed1d00c518>
[Errno -2] Name or service not known
something wrong

I tried resolving DNS resolve as suggested by stackoverflow answer.

What is the way around to fix this error? Why is urlopen or requests not working in kaggle kernels?
I have seen many kernels with the same errors kernel 1 kernel 2 kernel 3.

Solution

The reason this isn't working for you is because Kaggle Kernels currently don't currently have internet access. As a result, there's not a way for you to make API calls that require a network connection from within kernels.

Edit August 2018: Just FYI, we have now added internet access to Kernels. :) You can enable it in the left-hand side bar from within the editor.
