Python Data Science Jobs & Interviews

In Python, multiple inheritance allows a class to inherit from more than one parent class, enabling complex hierarchies but requiring careful management of method resolution order (MRO) to avoid conflicts. The MRO is determined using C3 linearization and can be inspected via the __mro__ attribute or mro() method.

class A:
    def greet(self):
        return "Hello from A"

class B:
    def greet(self):
        return "Hello from B"

class C(A, B):  # Inherits from A then B
    pass

c = C()
print(c.greet())  # "Hello from A" (A's method first in MRO)
print(C.__mro__)  # (<class '__main__.C'>, <class '__main__.A'>, <class '__main__.B'>, <class 'object'>)
