PyCharm Programming! A Game object knows its name and the number of avators is currently has. It is initialized without Avatars objects. It has a method startGame, which initializes an internal empty list of Avator objects. It has a method to add one Avator object at a time to the Game. It also has a method to remove an Avatar object by the Avatar’s name. A Game object also has a method to animate all its current Avatar objects. Furthermore, it has a method to stopGame, which destroys all current Avator objects in its internal list. The Avatar class creates simple human-type Avatars, which have attributes such as name, hair color, height, superpower. An Avatar object can change its hair color and superpower. It also has a method that “animates” the avatar. The animate() method should simply be a print message such as “Hello! I am …! I have…. hair and my super power is….!”, using the Avatar’s object variables. In main program, create 3 different Avatar objects that resemble 3…
