== PART 2 - Running System Launching Linux command and controlling its process Commands with os and subprocess modules ==:The remainder of this investigation will allow you to explore the behaviour of some built-in functions, all from the os and subprocess modules. All of them these functions will take function argument(s), some will return returnsvalue(s), but and some will not. The built-in functions we are going to explore are: os.system(), os.popen(), subprocess.Popen(). All of them can be used to issue operating system launching any Linux commandsand can interact the their processes.
