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：
