About
Python allows multiple inheritance, which can be useful but also confusing. To help you get started quickly, here’s a quick rundown of how to explicitly call parent class functions.
Multiple inheritance + ABC example with explicit init() calls
from abc import ABC, abstractmethod
class Base(ABC):
@abstractmethod
def do_something(self):
pass
class A(Base):
def __init__(self):
print("A.__init__")
def do_something(self):
print("A.do_something")
class B(Base):
def __init__(self):
print("B.__init__")
def do_something(self):
print("B.do_something")
class C(A, B):
def __init__(self):
print("C.__init__")
A.__init__(self)
B.__init__(self)
def do_something(self):
print("C.do_something")
A.do_something(self)
B.do_something(self)Call __init__ in super class with super
class Base:
def __init__(self, name):
print(f"Base.__init__: name = {name}")
self.name = name
class A(Base):
def __init__(self, name, age):
print(f"A.__init__: age = {age}")
super().__init__(name)
self.age = age
class B(Base):
def __init__(self, name, job):
print(f"B.__init__: job = {job}")
super().__init__(name)
self.job = job
class C(A, B):
def __init__(self, name, age, job):
print("C.__init__")
super().__init__(name, age)
B.__init__(self, name, job)
