I am trying to run something inside a Python file, and i do not want to see in the Python console the run output:
os.system("cd ../programs/{0} && ./run".format(project))
How can I do it? I tried with subprocess.call() but it does not compile.
Redirecting stdout to /dev/null:
import subprocess
subprocess.call(['./run'],
cwd=os.path.join('..', 'programs', project),
stdout=subprocess.DEVNULL)

I'm launching a programme with subprocess and follow that command with a for loop. The loop won't run until the programme I launched is closed. I don't understand why this is. Could someone please explain?
My Code:
import subprocess
import psutil
subprocess.call('/path_to/programme.exe')
for process in psutil.process_iter():
print(process)
I'm running Raspbian OS on a Pi 3 (armv7l).
Thanks for your time.

subprocess.call will wait until the command completes. Use subprocess.Popen instead.

Interacting with program after execution

I want a script to run an then finish on the python shell with all variables and methods:
$ python myprogram.py
...
program output
...
>>>
And with #!/usr/bin/python is posible? so I double-click and it just works?
Sounds like you want Python's i flag. From the help menu:
-i : inspect interactively after running script; forces a prompt even
if stdin does not appear to be a terminal; also PYTHONINSPECT=x
So the full command would be
python -i yourscriptname.py

I wanna to run my own non-system external commands in python.
Such as "sudo insteon on 23". Subprocess and os.system are designed for system calls.
Does anybody know how to do it?
Thanks
You can use subprocess.Popen for this:
import shlex
import subprocess
proc = subprocess.Popen(shlex.split('sudo insteon on 23'))
proc.communicate()
