Aim

Create a class that represents a portable movie player, MoviePlayer. The MoviePlayer class should have a play method, which sets the first movie from the list of movies as currently playing. The list of movies should be a private attribute. Additionally, it should have a firmware version attribute and an update firmware class method that updates the firmware version.

Steps for Completion

Go to your main.py file.

Define the MoviePlayer class by adding the firmware$\_$version class attribute and assigning it a value of $1\mathrm{.}0.$

Define the initializer method $\_\_$init$\_\_$ and pre$-$populate the movie list with a few movies. Make sure the movies store is private.

Define the play method, which sets the current$\_$movie attribute to the first item in the movies list.

Define the list$\_$movies method, which returns the list of movies in the MoviePlayer.

We'll add the update$\_$firmware version method, which checks for whether the new version being provided is more recent than the current firmware version before updating.

We then add a few test lines to the main method and run the script as shown in Snippet $7\mathrm{.}67$:

player $=$ MoviePlayer$()$

print$("$Movies currently on device:", player.list$\_$movies$())$

player.update$\_$firmware$(2\mathrm{.}0)$

print$("$Updated player firmware version to$",$ player.firmware$\_$version$)$

player.play$()$

print$("$Currently playing", f$"\text{'}\{$player$.$current$\_$movie$\}\text{'}")$

Snippet $7\mathrm{.}67$

We can run the script by entering python$3$ main.py in the terminal. The output should look similar to Figure $7\mathrm{.}6$:
