批處理如何關(guān)閉一個(gè)EXE執(zhí)行窗口

@echo off
:loop
setlocal enabledelayedexpansion
set py_exe=D:Python37pythonw.exe
set cmd1=D:test9.py
for /f tokens=1,2,3,4 delims=, %%a in (D:test925.txt) do (
ping -n 5 127.1>nul
start /wait %py_exe% %cmd1% %%a %%b %%c %%d
)
ping -n 10 127.1>nul
goto loop
pause>nul

批處理執(zhí)行時(shí),會(huì)循環(huán)跳出一個(gè)c/windows/py.exe標(biāo)題的CMD窗口,該如何在循環(huán)中執(zhí)行完一個(gè)命令,去關(guān)閉這個(gè)c/windows/py.exe標(biāo)題的CMD窗口呢?
