python3获取指定目录内容的详细信息
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%10.2fG\t%30s\t%30s\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%10.2fK\t%30s\t%30s\t%-20s' %('dir', info['Size'], time.ctime(info['TimeCreated']), time.ctime(info['TimeModified']), obj)) else: print('%-5s\t%10.2fM\t%30s\t%30s\t%-20s' %('dir', info['Size'], time.ctime(info['TimeCreated']), time.ctime(info['TimeModified']), obj)) else: #目录处理 info['TimeCreated'] = 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%10.2fG\t%30s\t%30s\t%-20s' %('file', info['Size'], time.ctime(info['TimeCreated']), time.ctime(info['TimeModified']), obj)) elif info['Size'] < 1: info['Size'] = info['Size'] * 1024 print('%-5s\t%10.2fK\t%30s\t%30s\t%-20s' %('file', info['Size'], time.ctime(info['TimeCreated']), time.ctime(info['TimeModified']), obj)) else: print('%-5s\t%10.2fM\t%30s\t%30s\t%-20s' %('dir', info['Size'], time.ctime(info['TimeCreated']), time.ctime(info['TimeModified']), obj)) if __name__ == '__main__': getFileInfo(sys.argv[1])

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！
