你如何在python中获得按创建日期排序的目录列表? [英] How do you get a directory listing sorted by creation date in python?

问题描述

获取目录中所有文件列表的最佳方法是什么，按日期排序[创建|修改]，在 Windows 机器上使用 python?

What is the best way to get a list of all files in a directory, sorted by date [created | modified], using python, on a windows machine?

推荐答案

更新:在 Python 3 中按修改日期对 dirpath 的条目进行排序:

Update: to sort dirpath's entries by modification date in Python 3:

import os
from pathlib import Path

paths = sorted(Path(dirpath).iterdir(), key=os.path.getmtime)

如果您已经有一个文件名列表files，那么在 Windows 上按创建时间对其进行就地排序(确保该列表包含绝对路径):

If you already have a list of filenames files, then to sort it inplace by creation time on Windows (make sure that list contains absolute path):

files.sort(key=os.path.getctime)

例如，使用 glob 可以获得的文件列表，如 @Jay 的回答所示.

The list of files you could get, for example, using glob as shown in @Jay's answer.

^旧答案这是 @Greg Hewgill 的回答.是最符合题型要求的.它区分了创建日期和修改日期(至少在 Windows 上是这样).

^{old answer} Here's a more verbose version of @Greg Hewgill's answer. It is the most conforming to the question requirements. It makes a distinction between creation and modification dates (at least on Windows).

#!/usr/bin/env python
from stat import S_ISREG, ST_CTIME, ST_MODE
import os, sys, time

# path to the directory (relative or absolute)
dirpath = sys.argv[1] if len(sys.argv) == 2 else r'.'

# get all entries in the directory w/ stats
entries = (os.path.join(dirpath, fn) for fn in os.listdir(dirpath))
entries = ((os.stat(path), path) for path in entries)

# leave only regular files, insert creation date
entries = ((stat[ST_CTIME], path)
           for stat, path in entries if S_ISREG(stat[ST_MODE]))
#NOTE: on Windows `ST_CTIME` is a creation date 
#  but on Unix it could be something else
#NOTE: use `ST_MTIME` to sort by a modification date
        
for cdate, path in sorted(entries):
    print time.ctime(cdate), os.path.basename(path)

示例:

$ python stat_creation_date.py
Thu Feb 11 13:31:07 2009 stat_creation_date.py
