*Python question

*here is example

def rotate90counterclockwise(): # Set up the source and target pictures file = pickAFile() pict = makePicture(file) wid = getWidth (pict) hgt = getHeight (pict) canvas = makeEmptyPicture(hgt, wid) # Now, do the actual copying--swap X & Y (correctly)! targetX = 1 for sourceX in range(1,getWidth(pict)): targetY = 1 for sourceY in range(1,getHeight(pict)): color = getColor(getPixel(pict,sourceX,sourceY)) setColor(getPixel(canvas, targetY, wid - targetX), color) targetY = targetY + 1 targetX = targetX + 1 show(pict) show(canvas) return canvas

*Write a function that takes any picture as an argument and rotates the given picture 180 degrees. You should create an empty canvas the same size as the original picture and it should contain the rotated image. Once you have rotated the image, display the new image.
