python subprocess become idle after a while

The script given below is I used for running as subprocess. subprocess . Popen ( "echo " + user_password + " | sudo -S " + filePath shell = True , stdout = subprocess . PIPE ) if i run serial port reading script manually, it will not idle, it runs contineously. But if i use the above script for running as subprocess, the serial port reading script become idle after a few minutes. How i can stop this idle issue? Ans:  I think, if you go for multi processing instead of subprocess, you don't get idle issue def executeOsCommand : os . system ( command ) command = "echo " + user_password + " | sudo -S " + filePath p = multiprocessing . Process ( target = executeOsCommand , args =( command ,)) p . start ()
