  • python--以1-31的数字作为结尾的列表?论英文好的重要性!

    一、python基础教程第2板(修订版)【代码清单2-1】中有一段要求打印‘以1-31的数字作为结尾的列表’  
      截取代码示例:
    endings =['st','nd','rd'] +17*['th'] + ['st','nd','rd'] +7*['th'] +['st']
      运行结果:print(endings)
        ['st', 'nd', 'rd', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'st', 'nd', 'rd', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'st']
    注:以上测试结果在Pycharm完成

       二、刚一开始疑虑为何列表可以那样写?稍加揣摩并Baidu了下,原来是英文的1-31天的英文末尾字符的简写,其中1-31天的英文对照如下:

       first (1st) 
       second (2nd) 
       third (3rd) 
       fourth (4th) 
       fifth (5th) 
       sixth (6th) 
       seventh (7th) 
       eighth (8th) 
       ninth (9th) 
       tenth (10th) 
       eleventh (11th) 
       twelfth (12th) 
       thirteenth (13th) 
       fourteenth (14th) 
       fifteenth (15th) 
       sixteenth (16th) 
       seventeenth (17th) 
       eighteenth (18th) 
       nineteenth (19th) 
       twentith(20th)
       twenty-first(21st)
       twenty-second(22nd)
       twenty-third(23rd)
       twenty-fourth(24th)
       twenty-fifth(25th)
       twenty-sixth(26th)
       twenty-seventh(27th)
       twenty-eighth(28th)
       twenty-ninth(29th)
       thirtith(30th)
       thirty-first(31st)

     三、由此可以看出英语在日常编码和学习的重要性,坚持编码的过程也要坚持学习English!
