Define the Artist class with a constructor to initialize an artist's information and a print$\_$info$()$ method. The constructor should by default initialize the artist's name to "unknown" and the years of birth and death to $-1.$ print$\_$info$()$ displays "Artist:", then a space, then the artist's name, then another space, then the birth and death dates in one of three formats:

$($XXXX to YYYY$)$ if both the birth and death years are nonnegative

$($XXXX to present$)$ if the birth year is nonnegative and the death year is negative

$($unknown$)$ otherwise

Define the Artwork class with a constructor to initialize an artwork's information and a print$\_$info$()$ method. The constructor should by default initialize the title to "unknown", the year created to $-1,$ and the artist to use the Artist default constructor parameter values.
