python获得磁盘剩余空间 statvfs［转］

Deprecated since version 2.6: The statvfs module has been deprecated for removal in Python 3.0.（Deprecated ：取缔）

The statvfs module defines constants so interpreting the result if os.statvfs(), which returns a tuple, can be made without remembering “magic numbers.” Each of the constants defined in this module is the index of the entry in the tuple returned by os.statvfs() that contains the specified information.

statvfs.F_BSIZE¶Preferred file system block size. statvfs.F_FRSIZE¶Fundamental file system block size. statvfs.F_BLOCKS¶Total number of blocks in the filesystem. statvfs.F_BFREE¶Total number of free blocks. statvfs.F_BAVAIL¶Free blocks available to non-super user. statvfs.F_FILES¶Total number of file nodes. statvfs.F_FFREE¶Total number of free file nodes. statvfs.F_FAVAIL¶Free nodes available to non-super user. statvfs.F_FLAG¶Flags. System dependent: see statvfs() man page. statvfs.F_NAMEMAX¶Maximum file name length.
如果用df 不好的话建议可以使用这个模块测试下。
