Now whenever you type
cls()
it will clear the screen and show the prompt at the top of the screen.

(The reason for the "x=" is: os.system returns a result, in this case 0.  When you evaluate an expression in the IDE, the IDE prints the result.  So without the "x=" you get an extra line at the top of the screen containing "0".)
Not if it's in a function, because the IDLE prints the result if it isn't None, and your function returns None. So:
     def cls():
         os.system("cls")
should be just fine.
