What is Python’s Method Resolution Order (MRO) and what algorithm computes it?

Accepted Answer

Python's Method Resolution Order (MRO) is the order in which Python searches classes for attribute/method lookup in multiple inheritance. It is computed by the C3 linearization algorithm, ensuring each class appears before its parents and preserving the order of base classes in the class definition.
