How do I use multiple inheritance in Python?

Multiple inheritance in Python allows a class to inherit from more than one parent class. You can define a class like this:

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

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

class Child(Parent1, Parent2):
    pass

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

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

In case of method name conflicts, Python follows the Method Resolution Order (MRO). The method from the first parent class listed will be called. You can check the MRO using Child.__mro__.

Can you give me an example of a conflict?

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

In this case, Child will use the greet method from Parent1.

How can I explicitly call a method from a specific parent class?

You can explicitly call a method from a specific parent class by using the class name. For example:

child_instance.Parent1.greet()  # Calls greet from Parent1
child_instance.Parent2.greet()  # Calls greet from Parent2
