Yes, but the file-like objects returned by python's urllib don't support
seek(), yet.

httplib is quite possible, and what the section that this example
prints, explains how it works:

from httplib import HTTPConnection

conn = HTTPConnection("www.ietf.org:80")

# Bytes form 100 onward
#conn.request("GET", "/rfc/rfc2616.txt", headers={"Range": "bytes=100-"})

# The RFC section describing the Range header
conn.request("GET", "/rfc/rfc2616.txt", headers={"Range": "bytes=336069-341643"})

# Last 100 bytes
#conn.request("GET", "/rfc/rfc2616.txt", headers={"Range": "bytes=-100"})

resp = conn.getresponse()
print resp.read()
