Explain Python's multiple inheritance and MRO.

Junior Python
Quick Answer Python supports multiple inheritance: class C(A, B). MRO (Method Resolution Order) determines which method to call using C3 linearization algorithm. Check with ClassName.__mro__ or ClassName.mro(). super() follows MRO correctly - critical for cooperative multiple inheritance. Diamond problem is resolved by MRO - each class appears once in the resolution order.

Answer

Python supports multiple inheritance.
MRO (Method Resolution Order) decides method lookup order.
Uses C3 linearization to avoid ambiguity.
Call C.mro() to check the resolution order.
