Executing Python script without hanging terminal

Question

Now this question might seem like an questions like this one and this one.

However unfortunately the above solutions don't work for me. I need a way to execute a Python 3.4.3 script, leave it running when the terminal closes, and have it not hang in terminal and executed directly.

pi@raspberrypi:/var/www/html/mysite/scripts $ nohup python3 my.script.py &

The above runs the script, but it hangs in terminal, I cannot enter any other commands until I stop it, by pressing CTRL + C.

Is there a way to achieve something like this:

pi@raspberrypi:/var/www/html/mysite/scripts $ nohup python3 my.script.py &
pi@raspberrypi:/var/www/html/mysite/scripts $ 
(Now I enter more commands, despite the script still running)

I hope I have provided enough information, hopefully you can help me, thanks!

Looks like you're just missing the ampersand. nohup python3 my.script.py& — user94559

With the ampersand, the script should run in the background. I'm not sure what more to tell you. Maybe copy/paste the exact command you executed? And tell us how you've determined that it's "hanging" the terminal? — user94559

Your script is really called my.script.py? I asked for an exact copy/paste because your initial post had the same line and was missing the ampersand, which would cause the issue you saw. "Extraordinary claims require extraordinary evidence." You're claiming that the ampersand doesn't cause the command to be executed in the background, so you're going to have to be very convincing with your evidence. — user94559

Based on a quick google search, I found

start /b python3 my.script.py

for windows or

python3 my.script.py &

on lunix (bash).

If the ampersand doesn't work, you can use a terminal multiplexer like GNU screen or tmux for your purpose.
