[Python] How to move desktop icons with python?

I am making a python program that moves the desktop icons using LVM_SETITEMPOSITION from winapi but I have a problem with commctrl.LVM_SETITEMPOSITION and it gives me an error 'int' object is not callable. Here is my code:

import win32gui
import commctrl
from time import sleep
from ctypes import wintypes

hd = wintypes.HWND

hd = win32gui.FindWindow("Progman", None)
hd = win32gui.FindWindowEx(hd, 0, "SHELLDLL_DefView", None)
hd = win32gui.FindWindowEx(hd, 0, "SysListView32", None)

i = 0
while i < 1000:
commctrl.LVM_SETITEMPOSITION(hd, 0, i, i)
i+100
sleep(1)
