What is the importance of MRO in Python?

MRO, or Method Resolution Order, determines the order in which base classes are searched when executing a method. It's crucial for ensuring that the correct method is called in complex inheritance scenarios.

Can you explain how MRO works with multiple inheritance?

Sure! In Python, MRO uses the C3 linearization algorithm to create a consistent order for method resolution. This ensures that each class is only called once and respects the order of inheritance.

What happens if there are conflicting methods in the base classes?

If there are conflicting methods, Python will follow the MRO to determine which method to call. The method from the first class in the MRO that defines the method will be executed.

How can I view the MRO of a class?

You can view the MRO of a class by using the __mro__ attribute or the mro() method. For example, MyClass.__mro__ will show you the MRO for MyClass.
