move turtle via arrows

import turtle;
t = turtle.Turtle();
w = turtle.Screen();

def right():
    t.right(45);

def left():
    t.left(45);

def up():
    t.forward( 2 );

def down():
    t.back( 2 );


w.onkey( right, "Right" );
w.onkey( left,  "Left"  );
w.onkey( up,    "Up"    );
w.onkey( down,  "Down"  );


w.listen();

This is like the most basic arbitrary example of turtle screen events. It is used strictly for teaching a beginner programmer some python basics.

Not to be used as a reference for my coding ability. I mean seriously guys. I would have to drink about 10 shots to numb my brain to the level of actually doing something useful with python.
