Properly Plural Python Printing

This one is kind of silly but sometimes you just want messages to use the proper plural case. Here is an example in Python 2 (with a little help from Qprompt):

import qprompt
num = qprompt.ask_int("How many beers?", vld=[1,2,3])
print "Okay, %u %s." % (
        num,
        "beer" if num == 1 else "beers")
