How does inheritance work in Python?

Question

Accepted Answer

Inheritance in Python lets a class derive attributes and behaviour from one or more parent (base) classes. The child class is-a specialized form of the parent, can add new members, and can override or extend existing ones. Basic syntax: class Animal: def __init__(self, name): self.name = name def speak(self): return "…" class Dog(Animal): def speak(self): return "woof" # override class Puppy(Dog): def speak(self): # extend via super() return super().speak() + "!" Multiple inheritance — Python supports it; a class can list several bases. Attribute lookup follows the MRO (Method Resolution Order), computed by the C3 linearization algorithm, viewable via Cls.__mro__ or help(Cls) . The MRO gives a deterministic, left-to-right, depth-first search that honors every parent’s ordering. MRO (Method Resolution Order) is the key concept for multiple inheritance. Know that super() follows MRO, not just the immediate parent. The diamond problem resolution (each class called once via C3 linearization) is commonly asked. Show __mro__ to inspect the order.
