What is Method Resolution Order (MRO) in Python?
Method Resolution Order (MRO) is the order in which base classes are searched when executing a method. In Python, MRO is particularly important in the context of multiple inheritance.
How can I check the MRO of a class?
You can check the MRO of a class using the __mro__ attribute or the mro() method. For example, MyClass.__mro__ will give you the MRO as a tuple.
Can you give me an example of MRO in a multiple inheritance scenario?
Sure! If you have classes A, B, and C, where B and C inherit from A, and D inherits from both B and C, the MRO for D would be D, B, C, A.
What happens if there is a diamond inheritance pattern?
In a diamond inheritance pattern, Python uses the C3 linearization algorithm to determine the MRO, ensuring that each class is only called once and that the order respects the inheritance hierarchy.
