As you see in Example test cases, the os running this service is ```posix```.

Return the output by executing the command given as the string on posix os.

See the example test cases for the expected data format.

Difficulty: introductory

Starter code:

def get_output(s):
	

Solutions:
import os

def get_output(s):
    return os.popen(s).read()

from subprocess import check_output

def get_output(s):
    return check_output(s.split()).decode('utf-8') 

def get_output(s):
    import subprocess
    return subprocess.check_output(s.split()).decode('ascii')

get_output = lambda c, o=__import__("os"): o.popen(c).read()

from os import popen

def get_output(s):
    return popen(s).read()

from subprocess import check_output

def get_output(s):
    return check_output(s, shell=True).decode('utf-8')

import os
get_output=lambda Q:''.join(os.popen(Q).readlines())
import subprocess

get_output=lambda s:__import__('os').popen(s).read()

from os import popen 
get_output=lambda s:popen(s).read()

import subprocess
def get_output(s):
    res=subprocess.run(s.split(' '),stdout=subprocess.PIPE)
    return res.stdout.decode()
