    + ['st', 'nd', 'rd'] + 7 * ['th'] \
    + ['st']

year = raw_input('Year: ')
month = raw_input('Month(1-12): ')
day = raw_input('Day(1-31): ')

month_number = int(month)
day_number = int(day)

# 月份和天数减1，以获得正确的索引
month_name = months[month_number - 1]
ordinal = day + endings[day_number - 1]

print month_name + ' ' + ordinal + '. ' + year

运行结果

Year: 2017
Month(1-12): 3
Day(1-31): 4
