AttributeError:module'ctypes.wintypes'没有属性'create_unicode_buffer'

Question

这是我的代码的一部分:

import os

def _get_appdata_path():
    import ctypes
    from ctypes import wintypes, windll
    CSIDL_APPDATA = 26
    _SHGetFolderPath = windll.shell32.SHGetFolderPathW
    _SHGetFolderPath.argtypes = [wintypes.HWND,
                                 ctypes.c_int,
                                 wintypes.HANDLE,
                                 wintypes.DWORD,
                                 wintypes.LPCWSTR]
    path_buf = wintypes.create_unicode_buffer(wintypes.MAX_PATH)
    result = _SHGetFolderPath(0, CSIDL_APPDATA, 0, 0, path_buf)
    return path_buf.value

但是当我打电话时,wintypes.create_unicode_buffer()我得到了错误:

AttributeError: module 'ctypes.wintypes' has no attribute 'create_unicode_buffer'

我使用的是Python 3.5.1.我能做什么？

使用ctypes.create_unicode_buffer,它在PY2和PY3中都有效.由于它的使用,它只是意外地在PY2中的wintypes from ctypes import *.:d
