Duck typing | Rustam Zokirov

The idea is that you don't need a type in order to invoke an existing method on an object - if a method is defined on it, you can invoke it

Duck Typing refers to the principle of not constraining or binding the code to specific data types.
We don’t care about the type of object, but we care about the methods and attributes the object include.

class Duck: 
    def __init__(self, name):
        self.name = name
    def quack(self):
        print('Quack!')

class Car: 
    def __init__(self, model):
        self.model = model
    
    def quack(self):
        print('I can quack, too!')


def quacks(obj):
    obj.quack()

>>> donald = Duck('Donald Duck')
>>> car = Car('Tesla')
>>>
>>> quacks(donald)
'Quack!'
>>>
>>> quacks(car)
'I can quack, too!'
