Question

efine 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 value

00:01 In this video, we will be creating a song class in python.

00:06 So to get started, we need to first create our class, which we are naming it a song.

00:13 Next, we want to create our constructor.

00:17 And the constructor in programming is used for instigating an object.

00:25 So to do this, we need to write a function and then our function name, which is i -n -i -t and then you want to do self and then the name of our variables we need.

00:53 So artist, genre, album, and now we do self -dartist equals artist, and we do the same for the rest.

01:16 So genre equals genre, album equals album, and lastly, self -dot month equals month.

01:36 All right.

01:38 Now we can come out of the constructor and we can create another function.

01:46 This function will be just songs and we're just going to return.

01:52 So we're returning self, artist, and all our other variables.

02:08 You can also include message, so artist, comma, oops, copy paste this.

02:23 We can change our message and variables accordingly.

02:30 Great.

02:31 I'm going to do genre, album, and length.

02:53 I can come out of here and that's pretty much it for our class.

02:59 We can then come out of our class and then create variables for our user.

03:06 So say our user wants to enter information.

03:14 So to do this, we need to get the input.

03:18 So enter artist, create variables for all of our variables...
