• save_compressed_image: takes a nested list and a filename (string) as input, and saves it in the compressed PGM format to a file with the given filename. If the image matrix given as input is not a valid compressed PGM image matrix, instead raise a AssertionError with an appropriate error message. >>> save_compressed_image([["0x5", "200x2"], ["111x7"]], "test.pgm.compressed") >>> fobj = open("test.pgm.compressed", 'r') >>> fobj.read() 'P2C\\n7 2\\n255\\n0x5 200x2\\n111x7\\n' >>> fobj.close() >>> image = [["0x5", "200x2"], ["111x7"]] >>> save_compressed_image(image, "test.pgm") >>> image2 = load_compressed_image("test.pgm") |>>> image == image2 True
