How do I hide the console when I use os.system() or subprocess.call()?

I wrote some statements like below: os.system(cmd) #do something subprocess.call('taskkill /F /IM exename.exe') both will pop up a console. How can I stop it from popping up the console?
The process STARTUPINFO can hide the console window: si = subprocess.STARTUPINFO() si.dwFlags |= subprocess.STARTF_USESHOWWINDOW #si.wShowWindow = subprocess.SW_HIDE # default subprocess.call('taskkill /F /IM exename.exe', startupinfo=si) Or set the creation flags to disable creating the window: CREATE_NO_WINDOW = 0x08000000 subprocess.call('taskkill /F /IM exename.exe', creationflags=CREATE_NO_WINDOW) The above is still a console process with valid handles for console I/O (verified by calling GetFileType on the handles returned by GetStdHandle). It just has no window and doesn't inherit the parent's console, if any. You can go a step farther by forcing the child to have no console at all: DETACHED_PROCESS = 0x00000008 subprocess.call('taskkill /F /IM exename.exe', creationflags=DETACHED_PROCESS) In this case the child's standard handles (i.e. GetStdHandle) are 0, but you can set them to an open disk file or pipe such as subprocess.DEVNULL (3.3) or subprocess.PIPE.
