Python实现获取磁盘剩余空间的2种方法

本文实例讲述了Python实现获取磁盘剩余空间的2种方法。分享给大家供大家参考，具体如下：

方法1：

import ctypes
import os
import platform
import sys
def get_free_space_mb(folder):
 """ Return folder/drive free space (in bytes)
 """
 if platform.system() == 'Windows':
   free_bytes = ctypes.c_ulonglong(0)
   ctypes.windll.kernel32.GetDiskFreeSpaceExW(ctypes.c_wchar_p(folder), None, None, ctypes.pointer(free_bytes))
   return free_bytes.value/1024/1024/1024
 else:
   st = os.statvfs(folder)
   return st.f_bavail * st.f_frsize/1024/1024
print(get_free_space_mb('C:\\'),'GB')

方法2：

import win32com.client as com
def TotalSize(drive):
 """ Return the TotalSize of a shared drive [GB]"""
 try:
   fso = com.Dispatch("Scripting.FileSystemObject")
   drv = fso.GetDrive(drive)
   return drv.TotalSize/2**30
 except:
   return 0
def FreeSpace(drive):
 """ Return the FreeSpace of a shared drive [GB]"""
 try:
   fso = com.Dispatch("Scripting.FileSystemObject")
   drv = fso.GetDrive(drive)
   return drv.FreeSpace/2**30
 except:
   return 0
workstations = ['dolphins']
print ('Hard drive sizes:')
for compName in workstations:
 drive = '\\\\' + compName + '\\c$'
 print ('*************************************************\n')
 print (compName)
 print ('TotalSize of ％s = ％f GB' ％ (drive, TotalSize(drive)))
 print ('FreeSpace on ％s = ％f GB' ％ (drive, FreeSpace(drive)))
 print ('*************************************************\n')

运行效果如下图：

希望本文所述对大家Python程序设计有所帮助。
