You can just change .py extension to .pyw
and the python file will run in background.
And if you want to terminate or check if it actually running in background,
simply open Task manager and go to Processes you will see python32 running
there.
EDIT
As you mentioned, this doesn't seem like working from command line because changing the file's .extension simply tells your system to open the file with pythonw application instead of python.
So when you are running this via command line as python .\run.pyw even with the .pyw this will run with python.exe instead of pythonw.exe.
Solution:
As you mentioned in the comments, run the file as pythonw .\run.pyw or .\run.py
or just double click the run.pyw file.
I'm using Task Scheduler to execute python run.py. It works, but the Python interpreter pops up. I want to run run.py in the background without any interpreter popping up.
How can I do this? In Linux I'd just do python run.py & to get it to run in the background silently, but I'm not sure how to achieve the same in Windows with Task Scheduler.
