检查目录是否是python 2.7的挂载点

Is there a pythonic way and without shell commands (i.e. with subprocess module) to check if a directory is a mount point?

是否有pythonic方式并且没有shell命令（即使用子进程模块）来检查目录是否是挂载点？

Up to now I use:

到目前为止我使用：

import os
import subprocess

def is_mount_point(dir_path):
    try:
        check_output([
            'mountpoint',
            path.realpath(dir_name)
        ])
        return True
    except CalledProcessError:
        return False

There is an os.path.ismount(path).

有一个os.path.ismount（路径）。

Return True if pathname path is a mount point: a point in a file system where a different file system has been mounted. The function checks whether path‘s parent, path/.., is on a different device than path, or whether path/.. and path point to the same i-node on the same device — this should detect mount points for all Unix and POSIX variants.

如果路径名路径是装入点，则返回True：文件系统中已装入其他文件系统的点。该函数检查路径的父路径，路径/ ..是否在与路径不同的设备上，或路径/ ..和路径是否指向同一设备上的同一个i节点 - 这应该检测所有Unix的挂载点和POSIX变种。

import os
os.path.ismount(dir_name)  # returns boolean

You may also refer to implementation (if you're on POSIX system). Check macpath.py or ntpath.py for other platforms.

您也可以参考实现（如果您使用的是POSIX系统）。检查macpath.py或ntpath.py以获取其他平台。
