Run os.system commands in new terminal - Python 3 on Raspberry Pi

Question

I am running a program which runs terminal codes based on the input recieved by the user on my Raspberry Pi. I want the process to run on a different terminal which is opened by my python code. For this on my Ubuntu machine I did

os.system("gnome-terminal -x google-chrome") #if i wanted to open chrome

But this is not an option on raspbian stretch. I want to know how I can perform similar functions on my raspberry pi

I had asked a similar question here . Refer to it to get a better understanding of what I am asking

I have Python 3.5.3 on the Raspberry Pi model 2 B running Raspbian Stretch

It sounds you do not necessarily want to spawn a new terminal emulator to run a process from, but just want that the process runs side-by-side with your Python code. You can spawn new processes in a more flexible way than os.system with the subprocess module.

import subprocess
subprocess.Popen("google-chrome", stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
# Python code continues executing as soon as the process is spawned
print("Hello, World!")

The stdout and stderr arguments state that the output should be discarded (ie redirected to /dev/null ).

Note that by default Popen does not use the shell to run your command. If you want to emulate the behaviour of os.system more closely, use shell=True as an argument to Popen . As with os.system this can have security implications!
