Python - open new shell and run command

Question

At the moment I am running a bash command from within Python using the following method:

os.system(cmd)

However I need to run the command in a new shell/terminal. Does anyone know how to do this?

Thanks, Dan

Answer 1

I am using the following method (this will also redirect stderr to stdout):

import subprocess    
cmd_line = "echo Hello!"
p = subprocess.Popen(cmd_line, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
out = p.communicate()[0]
print out

Answer 2

os.system() is deprecated in favour of :

import subprocess
print subprocess.check_output("command", shell=True)
