Write a function that will scale up just part of the picture. Try making someone’s nose longer.

What will be an ideal response?

```
def noseLongerifier (scr, x, y, w, h):
canvas = makeEmptyPicture(getWidth(scr), getHeight(scr))
for i in range(0, getWidth(scr)):
for j in range(0, getHeight(scr)):
p = getPixel(canvas, i, j)
p2 = getPixel(scr, i, j)
color = getColor(p2)
setColor(p, color)

sourceX = 0.0
for targetX in range(x,x+w*2):
sourceY = 0.0
for targetY in range(y,y+h):
px = getPixel(scr,int(sourceX),int(sourceY))
color = getColor(px)
setColor(getPixel(canvas ,int(targetX) ,int(targetY)), color)
sourceY = sourceY + 1
sourceX = sourceX + 0.5
show(canvas)
return canvas
```

Note: This function doubles the width of a past in area, so can be used to lengthen a nose.
