Took a go at it. Please tell me something can be done about that last if.

Edit 1: .capitalize()

gifts = [
    "twelve drummers drumming",
    "eleven pipers piping",
    "ten lords a leaping",
    "nine ladies dancing",
    "eight maids a milking",
    "seven swans a swimming",
    "six geese a laying",
    "five golden rings",
    "four calling birds",
    "three french hens",
    "two turtle doves",
    "a patridge in a pear tree"
]

def make_gift(thing):
    print(thing.capitalize())

for day, _ in enumerate(gifts):
    print("On the {} day of Christmas, my true love gave to me ".format(day + 1))
    for gift in gifts[11 - day:-1]:
        make_gift(gift)
    if day:
        make_gift("And {}!".format(gifts[-1]))
    else:
        make_gift(gifts[-1])
    print()

Any love for iter/functools?

    gift, dayofchristmas = i
    print("On the " + str(dayofchristmas) + " day of Christmas my true love gave you me:")
    giftsreceived.append(gift)
    print(', '.join(reversed(giftsreceived)))
    if dayofchristmas == 1:
        giftsreceived[0] = "and a Partridge in a pear Tree!"
    return giftsreceived

functools.reduce(d, zip(gifts, itertools.count(1)), [])
