Solving problem is about exposing yourself to as many situations as possible like How do I hide the console when I use os.system() or subprocess.call()? and practice these strategies over and over. With time, it becomes second nature and a natural way you approach any problems in general. Big or small, always start with a plan, use other strategies mentioned here till you are confident and ready to code the solution.
In this post, my aim is to share an overview the topic about How do I hide the console when I use os.system() or subprocess.call()?, which can be followed any time. Take easy to follow this discuss.
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?
Answer #1:
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.
Answer #2:
Add the shell=True argument to the subprocess calls.
subprocess.call('taskkill /F /IM exename.exe', shell=True)
Or, if you don’t need to wait for it, use subprocess.Popen rather than subprocess.call.
subprocess.Popen('taskkill /F /IM exename.exe', shell=True)
Answer #3:
Just add:
subprocess.call('powershell.exe taskkill /F /IM exename.exe', shell=True)
Answer #4:
Try to change the extension from .py to .pyw
Its basically just a Python User Interface file. So it opens up a new Window without the command line. chech this link (filext.com/file-extension/PYW)
Answer #5:
Try subprocess.Popen(["function","option1","option2"],shell=False).
