[python] ImportError: No module named request

I am trying to install python SpeechRecognition on my machine.When i am trying to install the package as pip install SpeechRecognition. I am getting the following error.

import json, urllib.request

ImportError: No module named request

And then i referred and installed requests as pip install requests i am i am getting Requirement already satisfied.But still i am unable to install SpeechRecognition.Please let me know what mistake i am doing.Thanks in advance

from @Zzmilanzz's answer I used

try: #python3
    from urllib.request import urlopen
except: #python2
    from urllib2 import urlopen

You can do that using Python 2.

1. Remove request
2. Make that line: from urllib2 import urlopen

You cannot have request in Python 2, you need to have Python 3 or above.
