17*[th] 生成 一个长度为17的列表，元素均为'th'。＋，将列表合并成一个大的列表。所以这行代码的作用时生成一个长度为31的后缀字符数组。这样就可以在day数字（1-31）后面 相应地加上后缀。如（1st, 2nd, 3rd, 4th, 5th, … , 19th, 20th, 21st, 22nd, 22rd, 23rd, 24th, … , 30th, 31st）。
>>> endings=['st','nd','rd']+17*['th']+['st','nd','rd']+7*['th']+['st']
>>> 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']
>>> endings=['st','nd','rd']+17*['th']+['st','nd','rd']+7*['th']+['st']
>>> 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']
