    inches_conv = input_cm * 2.54
    print "Centimeters: %f\n" % inches_conv
    time.sleep(3)
    restart = str(input("Do you wish to make another conversion? [y]Yes or [n]no: "))
    if restart == 'y':
        convert()
    elif restart == 'n':
        end_fast()
    else:
        print "I didn't quite understand that answer. Terminating."
        end_slow()

def end_fast():
    print "This program will close in 5 seconds."
    time.sleep(5)

def end_slow(): …
