Code Golf: Print the entire “12 Days of Christmas” song in the fewest lines of code

Answer 1

Python (71+467 including whitespaces)

import sys
sys.path += ["TDOC.zip"]
import TDOC
TDOC.print_verse()

Where TDOC.zip (467 bytes) contains TDOC.py:

def print_verse(presents="""\
twelve drummers drumming,
eleven pipers piping,
ten lords a-leaping,
nine ladies dancing,
eigth maids a-milking,
seven swans a-swimming,
six geese a-laying,
five gold rings,
four calling birds,
three french hens,
two turtle doves, and
a partridge in a pear tree.""".split("\n")):
    if presents: 
        print_verse(presents[1:])

        number = presents[0].split(" ", 1)[0]
        print("On the %s day of Christmas my true love gave to me %s" % (
            dict(a="first", two="second", three="third", five="fifth").get(number, number+"th"),
            " ".join(presents)))
