python获取文件属性-优快云博客

本文提供三种方法来获取文件的属性信息：使用os模块跨平台获取文件大小、最后访问时间等；通过win32api模块仅在Windows系统中检查文件是否只读或隐藏；利用win32api获取Windows文件的版本号。

提供三段代码

1、os模块

import os
def TestFileAttributes():
    # This function is platform indepedent.
    statinfo = os.stat("c:\\python26\\python.exe")   
    print statinfo.st_size
    print statinfo.st_atime
    print statinfo.st_mtime
    print statinfo.st_ctime
    #statinfo also include other linux specific information.   
    #print statinfo
TestFileAttributes()
#27136 #1299820024.28 #1228458748.0 #1228458748.0

2、调用win32api和win32con

import win32api,win32con
def TestWinFileAttributesIfReadonly():
    #This is just for windows.
    fattrs = win32api.GetFileAttributes("c:\\python26\\python.exe")
    #print fattrs
    print bool(fattrs & win32con.FILE_ATTRIBUTE_READONLY)
TestWinFileAttributesIfReadonly()
#False
def TestWinFileAttributesIfHidden():
    #This is just for windows.
    fattrs = win32api.GetFileAttributes("c:\\python26\\python.exe")
    #print fattrs
    print bool(fattrs & win32con.FILE_ATTRIBUTE_HIDDEN)
TestWinFileAttributesIfHidden() 
#False

3、win32api下的GetFileVersionInfo

from win32api import GetFileVersionInfo, LOWORD, HIWORD 
def get_version_number(filename):
    #This is just for windows.
    info = GetFileVersionInfo(filename, "\\")
    #print info
    ms = info['FileVersionMS']
    ls = info['FileVersionLS']
    print HIWORD (ms), LOWORD (ms), HIWORD (ls), LOWORD (ls)
get_version_number("C:\\Program Files\\7-Zip\\7z.exe")
