How to make a python, command-line program autocomplete arbitrary things

This entry is based on this SO post.
Problem
You have an interactive command-line Python script and you want to add autocompletion to it when hitting the TAB key.
Solution
Here is a working example (taken from here):
import readline
addrs = ['angela@domain.com', 'michael@domain.com', 'david@test.com']
def completer(text, state):
options = [x for x in addrs if x.startswith(text)]
try:
return options[state]
except IndexError:
return None
readline.set_completer(completer)
readline.parse_and_bind("tab: complete")
while True:
inp = raw_input("> ")
print "You entered", inp
