How can I implement multiple inheritance in Python?

In Python, you can implement multiple inheritance by defining a class that inherits from multiple parent classes. For example:

class Parent1:
    def method1(self):
        return 'Method from Parent1'

class Parent2:
    def method2(self):
        return 'Method from Parent2'

class Child(Parent1, Parent2):
    pass

child = Child()
print(child.method1())  # Output: Method from Parent1
print(child.method2())  # Output: Method from Parent2

What happens if there are methods with the same name in both parent classes?

If both parent classes have methods with the same name, Python uses the method resolution order (MRO) to determine which method to call. The method from the first parent class listed in the child class definition will take precedence.

Can you give an example of that?

Sure! Here's an example:

class Parent1:
    def greet(self):
        return 'Hello from Parent1'

class Parent2:
    def greet(self):
        return 'Hello from Parent2'

class Child(Parent1, Parent2):
    pass

child = Child()
print(child.greet())  # Output: Hello from Parent1

How can I control which method gets called?

You can control which method gets called by explicitly calling the method from a specific parent class using the class name:

child = Child()
print(Parent2.greet(child))  # Output: Hello from Parent2
