========= For UNIX =========
不过似乎有问题，怎么计算都不对。

import os
import statvfs

def free_bytes(path):
        stats = os.statvfs(path)
        return stats[statvfs.F_BSIZE] * stats[statvfs.F_BFREE]

def avail_bytes(path):
        stats = os.statvfs(path)
        return stats[statvfs.F_BSIZE] * stats[statvfs.F_BAVAIL]

def human_read(bytes):
        MB = bytes / (1024*1024)
        GB = MB / 1024
        MB = MB % 1024
        return "%dG %dM" % (GB, MB)

if __name__ == '__main__':
        import sys
        for path in sys.argv[1:]:
                print "%s:" % path,
                print "%s free," % human_read(free_bytes(path)),
                print "%s available" % human_read(avail_bytes(path))

========= For Win32 =========
import win32file

sectorsPerCluster, bytesPerSector, numFreeClusters, totalNumClusters = win32file.GetDiskFreeSpace("c:\\")
print "FreeSpace: ", (numFreeClusters * sectorsPerCluster * bytesPerSector) / (1024 * 1024), "MB"

ps.
貌似 module statvfs 在 py3000 中要被清除了，http://docs.python.org/library/statvfs.html
module win32file 需要自己安装一个 extension，http://sourceforge.net/projects/pywin32/
