1 Implement a new version of the gameoflife.py program to use your SparseLifeGrid class from the previous question.
2 Repeat Exercise 2.5 from Chapter 2 but use your new version of the gameoflife.py program from the previous question.
3 The digital grayscale image was introduced in Programming Project 2.3 and an abstract data type was de_ned and implemented for storing grayscale images.
A color digital image is also a two-dimensional raster image, but unlike the grayscale image, the pixels of a color image store data representing colors instead of a single grayscale value. There are di_erent ways to specify color, but one of the most common is with the use of the discrete RGB color space. Individual colors are speci_ed by three intensity values or components within the range [0 : : : 255], one for each of the three primary colors that represent the amount of red, green, and blue light that must be added to produce the given color. We can de_ne the RGBColor class for use in storing a single color in the discrete RGB color space.
class
RGBColor :
def
__init__( self, red = 0, green = 0, blue = 0 ):
self.red = red
self.green = green
self.blue = blue
Given the description of the operations for the Color Image ADT, implement the abstract data type using a 2-D array that stores instances of the RGBColor class. Note when setting the initial color in the constructor or when clearing the image to a speci_c color, you can store aliases to one RGBColor object in each element of the array.
_ ColorImage( nrows, ncols ): Creates a new instance that consists of nrows and ncols of pixels each set to black.
_ width(): Returns the width of the image.
_ height(): Returns the height of the image.
_ clear( color ): Clears the entire image by setting each pixel to the given RGB color.
_ getitem ( row, col ): Returns the RGB color of the given pixel as an RGBColor object. The pixel coordinates must be within the valid range.
_ setitem ( row, col, color ): Set the given pixel to the given RGB color. The pixel coordinates must be within the valid range.
