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 the parent classes have methods with the same name?

If the 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. You can check the MRO using Child.__mro__.

Can you give an example of that?

Sure! Here's an example:

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

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

class Child(Parent1, Parent2):
    pass

child = Child()
print(child.method())  # Output: Method from Parent1

In this case, Child will use method from Parent1.

How can I avoid issues with method name conflicts?

To avoid method name conflicts, you can use different method names in your parent classes or implement the super() function to call the desired parent class method explicitly. This way, you can control which method is executed.
