subprocess.Popen命令如何隐藏弹框

在用PYQT编写GUI界面时，代码中有用到subprocess.Popen()，打包exe后每次遇到subprocess语句是就会弹出命令框，很是头疼，

下面是解决的办法

import subprocess

st=subprocess.STARTUPINFO
st.dwFlags=subprocess.STARTF_USESHOWWINDOW
st.wShowWindow=subprocess.SW_HIDE

subprocess.Popen("adb devices", stdin=subprocess.PIPE,stdout=subprocess.PIPE, stderr=subprocess.PIPE,startupinfo=st)
