Python:

Write a program wipeDiagonalAnimation(picture) which takes as input a picture and creates an animation of the provided picture being wiped (black) top left to bottom right with 45degree diagonals. See the video for the desired effect.

Initialize all variables you may need.

Create a loop counting the diagonals. Use the dimension of the picture to determine the number of diagonals you need. Inside the loop draw a black diagonal with a loop or addLine. Note that the latter accepts negative values for the coordinates, which will make this exercise easier. Repaint your picture after a diagonal has been drawn.
