Define the Music class by adding the firmware_version class attribute. Define the initializer method and pre-populate the tracklist with the Spirit in the sky, Starman, and Escape songs. Make sure the music track's store is private. Define the play method, which sets the current_track attribute to the first item in the track's list. Define the list_tracks method, which returns the list of tracks in the Music class. Add the update_firmware method, which checks for whether the new version being provided is more recent than the current firmware version before updating. Output: Tracks currently on the device: ['Spirit in the sky', 'Starman', 'Escape'] Updated player firmware version to 2.0 Currently playing Spirit in the sky player = Music() print("Tracks currently on device", player.list_tracks() Music.update_firmware(2.0) print("Updated player firmware version to", player.firmware_version) player.play() print("Currently playing",player.current_track) Define the Music class by adding the firmware_version class attribute.
