clear_screen() function in Workspace vs. Spyder IDE

This is my first time utilizing the os and sys modules and I've noticed some differences of their effect when used in Spyder's IPython console vs. TeamTreehouse's Workspace. For example:

The following code neatly exits/quits Kenneth's script.

sys.exit

However, in Spyder this is the result of that call

UserWarning: To exit: use 'exit', 'quit', or Ctrl-D.
  warn("To exit: use 'exit', 'quit', or Ctrl-D.", stacklevel=1)
An exception has occurred, use %tb to see the full traceback.

Mind you the script does quit, but the interpreter doesn't seem to like it. Finally, it seem that my clear functions are not having the same effect if any in Spyder as it does in Workspace. The following code is meant to clear the screen for an enhanced UI experience.

def clear_screen():
    os.system("cls" if os.name == "nt" else "clear")

Nothing seems to be clearing. I guess I'm left a little lost on how this code would function in a standard IDE.

Thanks!
