不同平台获取指定目录内容的详细信息命令各不相同：
Linux中可以通过ls -al获取获取
windows中可以通过dir命令获取
下面是我写的一个通用获取目录内容详细信息的python3脚本：
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import os, time, sys
from os.path
import join, getsize
def ListDir(dir_data):
'''
:param dir_data: 指定获取内容的目录
每次返回目录下的一个文件或文件夹(生成器练习)
'''
list_dir =
os.listdir(dir_data)
while True:
try:
list_obj =
list_dir.pop()
yield dir_data, list_obj
except IndexError:
return
def GetDirSize(dir):
'''
:param dir: 指定获取大小的目录
获取目录大小
'''
size =
0
for root, dirs, files
in os.walk(dir):
size += sum([getsize(join(root, name))
for name
in files])
return size
def getFileInfo(dir_data):
'''
:param dir_data: 调用ListDir函数是所需参数
获取目录内的每个文件或目录的属性和大小并打印
'''
info =
{}
for root, obj
in ListDir(dir_data):
dir_obj =
'%s/%s' %
(root, obj)
if os.path.isfile(dir_obj):
#文件处理
'''info为字典格式，方便返回调用，此脚本只是输出内容，不涉及返回调用'''
info['TimeCreated'] = os.path.getctime(dir_obj)
#获取创建时间
info[
'TimeModified'] = os.path.getatime(dir_obj)
#获取访问时间
info[
'Size'] = os.path.getsize(dir_obj)/1024/1024
#获取文件大小，单位为M
if info[
'Size'] >= 1024:
#文件大小换算为G
info[
'Size'] = info[
'Size']/1014
print(
'%-5s\t.2fG\t0s\t0s\t%-20s' %(
'dir', info[
'Size'], time.ctime(info[
'TimeCreated']), time.ctime(info[
'TimeModified']), obj))
elif info[
'Size'] < 1:
#文件大小换算问K
info[
'Size'] = info[
'Size'] * 1024
print(
'%-5s\t.2fK\t0s\t0s\t%-20s' %(
'dir', info[

else:

else:
#目录处理

os.path.getctime(dir_obj)
info['TimeModified'] =
os.path.getatime(dir_obj)
info['Size'] = GetDirSize(dir_obj)/1024/1024
if info[
'Size'] >= 1024
:
info['Size'] = info[
'Size']/1014
print(
'%-5s\t.2fG\t0s\t0s\t%-20s' %(

elif info[
'Size'] < 1
:
info['Size'] = info[

print(

文件大小之计算到KB，不是太精确；大家有兴趣的可以精确到字节就完美了！
