我有一个列表lst，里面有大约100个tuples，看起来像这样：
[
('/var/www/html/wordpress/hyosyo/001.pdf','Thu Nov 7 18:07:52 2019'),('/var/www/html/wordpress/hyosyo/008.pdf','Thu Nov 7 18:08:24 2019'),('/var/www/html/wordpress/hyosyo/222.pdf','Thu Nov 7 18:10:10 2019'),('/var/www/html/wordpress/hyosyo/401.pdf','Fri Nov 8 09:00:39 2019')
]
此tuples包含一个string（文件名）和ctime的文件。我想查找5个最新日期（最新），并将其插入具有string名称的新列表中。
也许像这样：
import time
trg_arr = [ ('/var/www/html/wordpress/hyosyo/001.pdf','Thu Nov 20 18:07:52 2019') \,('/var/www/html/wordpress/hyosyo/008.pdf','Thu Nov 7 18:08:24 2019') \,('/var/www/html/wordpress/hyosyo/221.pdf','Thu Nov 7 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/222.pdf','Thu Nov 8 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/223.pdf','Thu Nov 9 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/224.pdf','Thu Nov 10 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/225.pdf','Thu Nov 11 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/226.pdf','Thu Nov 12 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/227.pdf','Thu Nov 13 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/228.pdf','Thu Nov 14 18:10:10 2019') \,('/var/www/html/wordpress/hyosyo/401.pdf','Fri Nov 8 09:00:39 2019')]
sorted_arr = sorted(trg_arr,key=lambda e: time.strptime(e[1]),reverse=True)
last_five = sorted_arr[:5]
print('Target list:')
print(trg_arr)
print('Sorted list:')
print(sorted_arr)
print('Last five:')
print(last_five)
