Вивчайте Multiple Inheritance

A class can be a subclass of a few other classes (inherit from multiple other classes).

To inherit from multiple classes, you can write the names of the classes separated by commas (,):


              123456789101112131415161718192021
            
class First:
    first_attribute = "First"

    def first_method(self):
        print("The first_method from the First class")
  
class Second:
    second_attribute = "Second"

    def second_method(self):
        print("The second_method from the Second class")

  
class Child(First, Second):
    pass

instance = Child()
print(instance.first_attribute)
print(instance.second_attribute)
instance.first_method()
instance.second_method()

But the multiple inheritance has an order. The priority of the attributes/methods search is going from left to right:


              1234567891011
            
class First:
    attribute = "First"
    
class Second:
    attribute = "Second"
    
class Child(Second, First):  # Order starts from the `Second`
    pass

instance = Child()
print(instance.attribute)

This demonstrates how the order of inheritance affects attribute resolution in cases where the same attribute is defined in multiple parent classes.
