Simple cli menu quits on selection

[sparkz_alot]

O.k., here is what I think is happening. Your "clear" command to clear the screen is preventing you from actually seeing the error, it erases the screen to fast for you to see. Try commenting the "os.system('clear')" and then run your script. 

Output:
Welcome,

Please choose the menu you want to start:

(1) Display operating system version
(2) Ping a web site
(Q) Quit

Enter your choice: 7
Not a correct choice: <7>,try again
Welcome,

Please choose the menu you want to start:

(1) Display operating system version

(Q) Quit

Enter your choice:

Either don't clear the screen, or add a time.sleep() after the 'print()'.
