Write a function to blend two pictures, starting with the top third of the first picture and then blend the two together in the middle third and then show the last third of the second picture. This works best if the two pictures are the same size.

Question

Assuming the same size in this response is acceptable

Answer 1

```
def blendTwoPictures(pict,secondPict):
firstThird = getHeight(pict)/3.0
secondThird = (2*getHeight(pict)/3.0)
for px in getPixels(pict):
x = getX(px)
y = getY(px)

if (y>firstThird) and (y redValOne = getRed(px)/2
greenValOne = getGreen(px)/2
blueValOne = getBlue(px)/2

secondPx = getPixel(secondPict,x,y)
redValTwo = getRed(secondPx)/2
greenValTwo = getGreen(secondPx)/2
blueValTwo = getBlue(secondPx)/2

setColor(px, makeColor(redValOne+redValTwo, greenValOne+greenValTwo,
blueValOne+blueValTwo))
elif (y>secondThird-1):
secondPx = getPixel(secondPict,x,y)
pxcol = getColor(secondPx)
setColor(px,pxcol)
```

Note: Since we just make changes to the first picture there’s no reason to do anything for the first third.
