Python索引示例

#根据给定的年月日以数字形式打印出日期
months = [‘Juanuary’,’February’,’March’,’April’,’May’,’June’,’July’,’Aygust’,
          ‘September’,’October’,’November’,’December’]
#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’]
#提示用户输入年月日      
year   = input(‘Year: ‘)
month  = input(‘Month (1-12): ‘)
day    = input(‘Day (1-31): ‘)

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

#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)
