【Pyhton】如何用python调用Windows属性窗口

代码：
import time
import ctypes
import ctypes.wintypes

SEE_MASK_NOCLOSEPROCESS = 0x00000040
SEE_MASK_INVOKEIDLIST = 0x0000000C

class SHELLEXECUTEINFO(ctypes.Structure):
    _fields_ = (
        ("cbSize",ctypes.wintypes.DWORD),
        ("fMask",ctypes.c_ulong),
        ("hwnd",ctypes.wintypes.HANDLE),
        ("lpVerb",ctypes.c_char_p),
        ("lpFile",ctypes.c_char_p),
        ("lpParameters",ctypes.c_char_p),
        ("lpDirectory",ctypes.c_char_p),
        ("nShow",ctypes.c_int),
        ("hInstApp",ctypes.wintypes.HINSTANCE),
        ("lpIDList",ctypes.c_void_p),
        ("lpClass",ctypes.c_char_p),
        ("hKeyClass",ctypes.wintypes.HKEY),
        ("dwHotKey",ctypes.wintypes.DWORD),
        ("hIconOrMonitor",ctypes.wintypes.HANDLE),
        ("hProcess",ctypes.wintypes.HANDLE),
    )

ShellExecuteEx = ctypes.windll.shell32.ShellExecuteEx
ShellExecuteEx.restype = ctypes.wintypes.BOOL

sei = SHELLEXECUTEINFO()
sei.cbSize = ctypes.sizeof(sei)
sei.fMask = SEE_MASK_NOCLOSEPROCESS | SEE_MASK_INVOKEIDLIST
sei.lpVerb = "properties".encode('utf-8')
sei.lpFile = r'I:\1.txt'.encode('utf-8')#这里填上你要查看的文件路径，由于python环境不同我这边必须得加上.encode('utf-8')，如有异常的话删除后试试。sei.nShow = 1
ShellExecuteEx(ctypes.byref(sei))
time.sleep(5)

我这边的报错TypeError: bytes or integer address expected instead of str instance
