获取文件夹中的第二个最新文件

Question

I am trying to get most recent and second most recent file in a directory. here is my code

import glob
import os

path = r'C:\temp\Processed\*'
list_of_files = glob.glob(path) # * means all if need specific format then *.csv
sorted_files = sorted(list_of_files, key=os.path.getctime)
print sorted_files[-1]
print sorted_files[-2]

Reference: Second newest file

latest_file[-1] returns the newest file ( 170608_191655__Equity_Watched.csv ), but latest_file[-2] gives me a 170607_082445__Equity_Watched.csv which is not the second most recent. I was expecting to get 170607_231353__Equity_Watched.csv .

Any idea what am I doing wrong?

Answer 1

看起来您实际上想要的是getmtime ，而不是getctime （因为您正在向我们展示一个显示修改时间的屏幕截图）。

Answer 2

Hmm, here are a couple ways to possible go about it.

1. Reverse the sort. Sort it in the other direction and try accessing sorted_list[0] and sorted_list[1] . Maybe that will give you a more promising result
2. Access file in the list and sort yourself. You could loop through the list, run os.path.getctime on them, and use that data to find the recent and second most recent items yourself.
3. Continue to google or wait on another answer. Or use getmtime as Stefan mentioned...

Best of luck!

Answer 3

sorted_files = sorted(list_of_files, key=os.path.getmtime)
print sorted_files[-2]
