Make 2 monster subclasses: Dragon and ghosts, both of which inherit all of the properties of the Monster class. Both should have their "type" attribute updated to ‘dragon’ and ‘ghost’ respectively. Dragon and ghosts have the ability to level up! Every time a dragon gains 10 exp all of its attacks gain +1 damage. For Example, at 30 exp a dragon's attack will have each +3 damage total. This does NOT include any new attacks learned after gaining exp. For Ghosts, every time a Ghost gains 10exp it gains +5 to its max_hp and therefore current_hp. In order to implement this, change the win_fight and lose_fight methods within each subclass to account for these changes. There is no need to change the Monster class or the monster_fight function.
