turtle.onkeypress(fun, key=None)
Parameters:

• fun – a function with no arguments or None
  
• key – a string: key (e.g. “a”) or key-symbol (e.g. “space”)
  

Bind fun to key-press event of key if key is given, or to any key-press-event if no key is given. Remark: in order to be able to register key-events, TurtleScreen must have focus. (See method listen().)

>>> def f():
...     fd(50)
...
>>> screen.onkey(f, "Up")
>>> screen.listen()
