months = [
    'January',
    'February',
    'March',
    'April',
    'May',
    'June',

#以1-31的数字作为结尾的列表
endings = ['st','nd','rd'] + 17 * ['th'] \
        + ['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)

#记得要将月份和天数减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

执行结果：

[root@localhost script]# python 1.py
year: 1942
Month(1-12): 12
Day(1-31): 1
