Multiple Inheritance and Method Resolution Order (MRO):
In Simple Words:
Python resolves multiple inheritance orders using the C3 Linearization Algorithm (depth-first, left-to-right, preserving local precedence). Check it with ClassName.mro().
python
class A: pass
class B(A): pass
class C(A): pass
class D(B, C): pass
print([cls.__name__ for cls in D.mro()])
# Output: ['D', 'B', 'C', 'A', 'object']
