棣小天儿的第一个python程序

根据给定的年月日，以数字形式打印出日期

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

    'June',
    'July',
    'August',
    'September',
    'October',
    'November',

]
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)

month_name = months[month_number-1]
ordinal = day + endings[day_number-1]

print month_name + ' ' + ordinal + ', ' + year

Year: 2017

Month(1~12): 10

Day(1~31): 12
