● load_regular_image: takes a filename (string) of a PGM image file as input, and loads in the image contained in the file and returns it as an image matrix. If, during or after loading, the resulting image matrix is found to not be in PGM format, then a AssertionError with an appropriate error message should be raised instead. (The file could have anything inside it, not necessarily a valid image matrix.) Note: For this and further examples, we put each sublist on its own line for readability purposes. When you write your examples in the docstring, however, the output must be all on one line for the doctest to work properly.
