Look at urllib2.

Even better, look at requests 
(http://docs.python-requests.org/en/latest/).  There's nothing you can 
do with requests that you can't do with urllib2, but the interface is a 
whole lot easier to work with.

There is also a httplib2 module 
https://code.google.com/p/httplib2/

Both are Pythonic, and power is irrelevant for this.  Your code is going to
spend 90% of its time waiting for the network.  Just solve the problem.
