Finish the Joe the Box example.

Question

(a) Implement grow and move. The method move takes as input a relative distance like (?10,15) to move 10 pixels left (x position) and 15 pixels down (y position).
(b) Draw patterns by creating joe and jane, then move a little and draw, grow a little and draw, then repaint the new canvas.

Answer 1

(a) ```
class Box:

def move(self, x, y):
xPos = self.position[0]
yPos = self.position[1]
xPos = xPos + x
yPos = yPos + y

self.position = (xPos, yPos)
```

(b) ```
def makePattern():
jane = SadBox ()
joe = Box ()
canvas = makeEmptyPicture(300,300)
canvas.show()
for i in range(0, 30):
jane.move(i, 0)
joe.move(0,i)
jane.draw(canvas)
joe.draw(canvas)

repaint(canvas)
joe.grow(i)
jane.grow(i)
jane.draw(canvas)
joe.draw(canvas)

repaint(canvas)
```
