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：
