As far as I can tell, my code looks correct, but when I try to run it in Shell, I get the error 'Unexpected Character After Line Continutation Character' and a long space after the last print is highlighted. Hitting backspace deletes the last ), in the print function before main, so I'm not entirely sure how to fix it, and I haven't encountered this syntax error before.
