Use Multiple Inheritance to Combine Two Parent Behaviors

You will build a small class hierarchy that demonstrates cooperative multiple inheritance in Python. Create an Animal base class and two behavior mixin-like parents, Flyer and Swimmer. Each parent should accept and store its own initialization parameter and should cooperate with other classes using super() and keyword arguments so that a concrete child class Duck can inherit both behaviors without duplicated initialization. The Duck class should: - Initialize name (from Animal), wing_span (from Flyer) and swim_speed (from Swimmer) using cooperative multiple inheritance (super() and keyword args). - Provide a moves() method that returns a list of action strings in the order: flyer action first, swimmer action second. - Provide a describe() method that returns a single string in the form: "{name}: fly({wing_span}), swim({swim_speed})". Do not call parent __init__ methods directly by name (e.g., Flyer.__init__(...)). Use super() and keyword arguments so the hierarchy remains cooperative and safe for further subclassing.

Implement parent classes that cooperate via super() and a child class that combines both behaviors without duplicating initialization or breaking the method resolution order.

Use cooperative multiple inheritance. Each parent class must call super().__init__(**kwargs) so that Duck can initialize all required attributes by calling super().__init__(name=..., wing_span=..., swim_speed=...). Do not directly invoke parent class __init__ by class name.
