Command prompt result in label. Python 2.7 -

i want put result(output) of shell command label. command works, label shows "0", however, in command prompt, result shown correctly, need showed in label. doing ubuntu.

 myg1 = button(root, text="rodyti informacija", command=lambda: gauti())     myg1.pack(side=bottom)   def gauti():         imti = tekstas.get("1.0", "end-1c")         info = subprocess.call("id '{imti}' ".format(imti=imti), shell=true)         w = label(root, text= info)         w.pack(side = bottom) 

subprocess.call() returns exit code of process created (in case 0 success). if want text output of process, should instead call subprocess.check_output().
