The Magic Square is a grid with 3 rows and 3 columns with the following properties: • The grid contains every number from 1 to 9

. • The sum of each row, each column, and each diagonal all add up to the same number. This is an example of a Magic Square: 4 9 2 3 5 7 8 1 6 You can simulate a 3x3 grid using a two-dimensional list. For example, the list corresponding to the grid above would be: [[4, 9, 2], [3, 5, 7], [8, 1, 6]] Write a function that accepts a two-dimensional list as an argument and returns whether the list represents a Magic Square (either True or False). Create a program that tests the function on the following two-dimensional lists and prints out the results each on a separate line: [[4, 9, 2], [3, 5, 7], [8, 1, 6]] [[2, 7, 6], [9, 5, 1], [4, 3, 8]] [[1, 2, 3], [4, 5, 6], [7, 8, 9]] [[4, 9, 2], [3, 5, 5], [8, 1, 6]]

nika2105 [10]

Answer:

class Artist():

   def __init__(self, artist_name=None, artist_birth_year=0, artist_death_year=0):

       self.artist_name = artist_name

       self.artist_birth_year = artist_birth_year

       self.artist_death_year = artist_death_year

   def display_artist(self):

       if self.artist_death_year == -1:

           print('{}, born {}'.format(self.artist_name, self.artist_birth_year))

       else:

           print('{} ({}-{})'.format(self.artist_name, self.artist_birth_year, self.artist_death_year))

class Artwork():

   def __init__(self, artwork_title=None, artwork_year_created=0, artist=Artist()):

       self.artwork_title = artwork_title

       self.artwork_year_created = artwork_year_created

       self.artist = artist

   def display_artist(self):

       print('artwork_title: {}'.format(self.artwork_title))

       print('Artist: ', end='')

       self.artist.display_artist()

def main():

   user_artist_name = input('Enter the name of artist: ')

   user_birth_year = int(input('Enter birth year: '))

   user_death_year = int(input('Enter death year: '))

   user_title = input('Enter master piece title: ')

   user_year_created = int(input('Enter year created: '))

   user_artist = Artist(user_artist_name, user_birth_year, user_death_year)

   new_artwork = Artwork(user_title, user_year_created, user_artist)

   new_artwork.display_artist()

if __name__ == "__main__":

   main()

Explanation:  

  • Inside the constructor of Artist class, initialize the essential properties.
  • Create the display_artist function that checks whether artist_death_year is equal to -1 and then displays an appropriate message according to the condition.
  • Apply the similar steps as above for the Artwork class.
  • Inside the main method, get the information from user and finally call the display_artist function to print the results on screen.
