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?
