Python Save Sets To File On Windows Shutdown?
(2 answers)
Closed 4 years ago.
I would like to know how to "cleanly" finish the execution of a python application on Windows shutdown.
My application starts at startup, opens a text file and keeps running while Windows is on, What I want to do is to, somehow, capture the shutdown signal and inmediately stop the processes running and close the text file with the io method myFile.close(), finishing the program by itself, and not forced by Windows. Any idea about how that could be done?
Thank you in advance.
Regards

How to run a python script in the background?
(6 answers)
Closed 7 years ago.
I have been trying to code a python script which reads data from a serial port. It worked well from the command line but I need it to run as a background process without any command line interface. The script has a while loop which reads the next byte of data from a serial port and simulates a key press accordingly. For the keypresses to be focused on the current window, instead of python command line, I need the script to run as a background process. I have read few answers here but nothing rang a bell for me. Please point me in the right direction.
On Windows, you can run a Python script in the background using the pythonw.exe executable, which will run your program with no visible process or way to interact with it. You also cannot terminate it without a system monitor. More information on pythonw.exe can be found in the answers to the question: pythonw.exe or python.exe?

Non blocking subprocess.call

I'm launching a programme with subprocess and follow that command with a for loop. The loop won't run until the programme I launched is closed. I don't understand why this is. Could someone please explain?
My Code:
import subprocess
import psutil
subprocess.call('/path_to/programme.exe')
for process in psutil.process_iter():
print(process)
I'm running Raspbian OS on a Pi 3 (armv7l).
Thanks for your time.

subprocess.call will wait until the command completes. Use subprocess.Popen instead.

Just wondering if there's a way to close the terminal with a python script in an if else statement. I know how to exit a program with "exit( 0 )" but is there a way to actually close the terminal, like when you hit "X" or Alt + F4?
Thanks! (I'm new to python so I don't know much, sorry.)

Run python script without DOS shell appearing
I have a python script that Windows Scheduler runs every 5 minutes for me. The script works fine but every time it runs it's loading up the console really quick on my desktop before it automatically closes. Does anyone know how to remove this behavior? I'd like it to just run in the background without me knowing.
Run it through pythonw instead of python (pyw if you're using the new launcher).
