Thanks for the 'input' :.P

Ah, yes I see what's happening, the last time I was doing it I was using:
...........KEYDOWN:
if event.key == K_LEFT:
   foreward = True
...........KEYUP:
if event.key == K_LEFT:
   foreward = False
meaning it was staying true, until key up but now it's not keeping the 
output next time round & waiting for it again.
could you elaborate on this bit 'You could make the character move every 
frame (eg. setting a speed and
moving by that speed per frame) until a KEYUP event happens', or is that 
pretty much what I 'was' doing?

My aim is to keep the input controls as a completely separate (independent & 
reusable) module, i'm not sure how using True & False is workable.

Could I use "keys_down = pygame.key.get_pressed" then
                     "if keys_down[K_RIGHT] ## move right",

in this way:
class character():
................
   def update(self, d, sp):
       if d == 6:
           self.x += sp
       elif d == 4:
           self.x -= sp
       elif d == 8:
           self.y -= sp
       elif d == 2:
           self.y += sp

main loop:
while True:
   Display.window.fill((0, 0, 0))

   D = Keyboard.controls()
   ball.draw(100, 100)
   ball.update(D, 1)

controls:
def controls():

   output = 0
   keysDown = pygame.key.get_pressed():
   if keysDown[K_RIGHT]:
       output = 6
