Arbitrary object importation.
# 'pkg_name' is the name of a package/module. May be dotted
# 'obj_name' is the name of an object within said package.
# Why there isn't a straightforward function in the standard library for dealing with this already boggles my mind.
obj = __import__(pkg_name, fromlist=[object_name.split('.', 1)[0]])
for segment in object_name.split('.'):
obj = getattr(obj, segment)

Using urllib2 with Basic auth (because I can never remember the silly dance that has to be done).
import urllib2
mgr = urllib2.HTTPPasswordMgr()
mgr.add_password('realm', 'http://example.com/base/', 'username', 'password')
urllib2.install_opener(urllib2.build_opener(urllib2.HTTPBasicAuthHandler(mgr)))
urllib2.urlopen('http://example.com/base/something/')

Given an IP address (either IPv4 or IPv6) and an array of IP ranges in CIDR notation, check if the given address is in any of those ranges.
<?php

foreach ($ranges as $range) {
$parts = explode('/', $range, 2);
$chunked_range = to_chunked_ip($parts[0]);
