Thankyou goodsir. This is what I was looking to do.

Not quite sure if it helped to be honest. I consulted documentation and fixed it up a bit.

class draw:
    def __init__(self, col, x, y):
        Turtle.__init__(self)
        self.color(col)
        self.shape("circle")
        self.goto(0, 0)
        pd()
        width(7)
    
        
        
def U():
    fd(8)
    onkey(U, "Up")
    listen()
    
def L():
    lt(8)
    onkey(L, "Left")
    listen()

def R():
    rt(8)
    onkey(R, "Right")
    listen()

def D():
    bk(8)
    onkey(D, "Down")
    listen()

I just still cant get it to draw is all.
