urllib.request in Python 2.7

I can use urllib.request module with Python 3.1. But when I execute the same program using Python 2.7, an error comes along the lines of;

AttributeError: 'module' object has no attribute 'request'.

I believe this error is because theres no request module in urllib for Python 2.7. Because I need to use tweepy i'll have to stick with Python 2.7 since tweepy does not support Python 3.

So how I can use urllib.request module in Python 2.7?
