[Tutor] about the function

[Kent Johnson]

If I understand your question, it sounds like maybe pic should be a class. 
Then it would keep its position in instance variable and draw itself. Your 
code would be
   pic.setposition(position)
   pic.draw()

Otherwise setposition(position, pic) could modify pic in some way so that 
draw(pic) knows where to draw it. Or you could pass the position to draw: 
draw(pic, position)

More detail about pic would help.
