Here are some code examples from the book, written by Alex McLean.

#!/usr/bin/python
# A script for greeting every server on the Internet.
import iptools, httplib
for ip in iptools.IpRangeList('0.0.0.0/0'):
try:
print "Greeting " + ip
cx = httplib.HTTPConnection("%s:80" % ip)
cx.request("POST", '/', "message=Hello+world!")
except:
pass
