Python modules sometimes give issues. We got below warning from a python application. /usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/util/ssl_.py:120: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.

Blogs and news sites use RSS(Rich Site Summary) feeds. Python can be used to fetch updates. I have written a simple program which can fetch RSS feed and print links. I have written the same application in both Python 2.7 and Python 3 both In Python 3, urllib2.urlopen() is replaced with urllib.request.urlopen(). Python 3 code is mentioned below.
