Program Plan:

$1.$ Artist.py:

Class Artist:

Constructor init: Initializes artist attributes: name, birth$\_$year, and death$\_$year. If not provided, defaults are used.

Method print$\_$info: Prints the artist's name, birth year, and death year or mentions "present" if the artist is still alive.

$2.$ Artwork.py:

Import:

Import the Artist class from Artist.py$.$

Class Artwork:

Constructor init: Initializes artwork attributes: title, year$\_$created, and the associated artist object.

Method print$\_$info: Prints the artwork's title and year created. Calls the Artist's print$\_$info method to print the artist's details.

$3.$ main.py:

Main Function:

Reads user input for an artist's name, birth year, and death year.

Reads user input for artwork title and year of creation.

Creates an Artist object using the provided artist details.

Creates an Artwork object using the provided artwork details and the created Artist object.

Calls print$\_$info on the Artwork object to display both artwork and artist information.

Step $2$ of $2$

The required code snippets are as follows:

Artist.py

class Artist:

# Constructor that initializes the Artist's name, birth year, and death year

def $\_\_$init$\_\_($self$,$ name $=$ "unknown", birth$\_$year $=-1,$ death$\_$year $=-1)->$ None:

# Assign name, birth year, and death year to the instance attributes

self.name $=$ name

self.birth$\_$year $=$ birth$\_$year

self.death$\_$year $=$ death$\_$year

# Method to print the artist's information based on the provided birth and death years

def print$\_$info$($self$)$:

# If both birth year and death year are valid, print them

if self.birth$\_$year $>0$ and self.death$\_$year $>=0$:

print$($f$\text{'}$Artist: $\{$self$.$name$\}(\{$self$.$birth$\_$year$\}$ to $\{$self$.$death$\_$year$\})\text{'})$

# If only birth year is known and artist is still alive, print "present"

elif self.birth$\_$year $>=0$:

print$($f$\text{'}$Artist: $\{$self$.$name$\},(\{$self$.$birth$\_$year$\}-$ present$)\text{'})$

# If no valid birth year is provided, print "unknown"

else:

print$($f$\text{'}$Artist: $\{$self$.$name$\}($unknown$)\text{'})$

Artwork.py

from Artist import Artist # Import the Artist class for use within Artwork

class Artwork:

# Constructor that initializes the title, year of creation, and associated artist

def $\_\_$init$\_\_($self$,$ title $=$ "unknown", year$\_$created $=-1,$ artist $=$ Artist$())->$ None:

# Assign title, year of creation, and associated artist to the instance attributes

self.title $=$ title

self.year$\_$created $=$ year$\_$created

self.artist $=$ artist

# Method to print the artwork's information along with the artist's details

def print$\_$info$($self$)$:

self.artist.print$\_$info$()$ # Call the artist's print$\_$info method to display artist details

# Print the artwork's title and the year it was created

print$($f$\text{'}$Title: $\{$self$.$title$\},\{$self$.$year$\_$created$\}\text{'})$

Main.py

# Import the Artist and Artwork classes

from Artist import Artist

from Artwork import Artwork

# Entry point of the program

if $\_\_$name$\_\_=="\_\_$main$\_\_"$:

# Read the artist's name from user input

user$\_$artist$\_$name $=$ input$()$

# Read the artist's birth year from user input $($converted to integer$)$

user$\_$birth$\_$year $=$ int$($input$())$

# Read the artist's death year from user input $($converted to integer$)$

user$\_$death$\_$year $=$ int$($input$())$

# Read the artwork's title from user input

user$\_$title $=$ input$()$

# Read the year the artwork was created from user input $($converted to integer$)$

user$\_$year$\_$created $=$ int$($input$())$

# Create an Artist object using the provided name, birth year, and death year

user$\_$artist $=$ Artist$($user$\_$artist$\_$name, user$\_$birth$\_$year, user$\_$death$\_$year$)$

# Create an Artwork object using the title, year created, and the associated artist

new$\_$artwork $=$ Artwork$($user$\_$title, user$\_$year$\_$created, user$\_$artist$)$

# Print the complete artwork information $($including artist details$)$

new$\_$artwork.print$\_$info$()$

Final solution

The sample outputs are as follows:
