Can you explain what Method Resolution Order (MRO) is in Python?
Sure! Method Resolution Order (MRO) is the order in which Python looks for a method in a hierarchy of classes. It determines the sequence of classes that Python will search when a method is called.
How does MRO work with multiple inheritance?
In multiple inheritance, Python uses the C3 linearization algorithm to determine the MRO. This ensures a consistent order that respects the inheritance hierarchy.
Can you give me an example of MRO in action?
Absolutely! Consider classes A, B, and C where B and C inherit from A. If you create a class D that inherits from both B and C, the MRO will be A, B, C, D. You can check this using the __mro__
attribute.
What happens if there are conflicting methods in the parent classes?
In case of conflicting methods, Python will follow the MRO to resolve which method to call. The method from the first class in the MRO that defines the method will be executed.
