python - 使用 python3.x 在 Linux 中查看分区

Question

最近我刚开始使用python3，发现python2.6 有很多变化。我想知道是否有通过使用 fdisk 格式化 linux 系统中可用硬盘的 View ？在 python2.6 中，它是这样工作的；

def parse_fdisk(fdisk_output):
    result = {}
    for line in fdisk_output.split("\n"):
        if not line.startswith("/"): continue
        parts = line.split()

        inf = {}
        if parts[1] == "*":
            inf['bootable'] = True
            del parts[1]

        else:
            inf['bootable'] = False

        inf['start'] = int(parts[1])
        inf['end'] = int(parts[2])
        inf['blocks'] = int(parts[3].rstrip("+"))
        inf['partition_id'] = int(parts[4], 16)
        inf['partition_id_string'] = " ".join(parts[5:])

        result[parts[0]] = inf
    return result

def main():
    fdisk_output = commands.getoutput("fdisk -l")
    for disk, info in parse_fdisk(fdisk_output).items():
        print disk, " ".join(["%s=%r" % i for i in info.items()])

看看 psutil包裹。

psutil is a module providing an interface for retrieving information on all running processes and system utilization (CPU, disk, memory) in a portable way by using Python, implementing many functionalities offered by command line tools such as: ps, top, df, kill, free, lsof, netstat, ifconfig, nice, ionice, iostat, iotop, uptime, tty.

来自他们的 README :

It currently supports Linux, Windows, OSX and FreeBSD both 32-bit and 64-bit with Python versions from 2.4 to 3.3 by using a single code base.

磁盘示例:

>>> psutil.disk_partitions()
[partition(device='/dev/sda1', mountpoint='/', fstype='ext4'),
 partition(device='/dev/sda2', mountpoint='/home', fstype='ext4')]
>>>
>>> psutil.disk_usage('/')
usage(total=21378641920, used=4809781248, free=15482871808, percent=22.5)
>>>
>>> psutil.disk_io_counters()
iostat(read_count=719566, write_count=1082197, read_bytes=18626220032, 
       write_bytes=24081764352, read_time=5023392, write_time=63199568)

据我所知，(目前)还不支持分区详细信息(例如可引导标志)。
