How to invoke the super constructor in Python?


In line with the other answers, there are multiple ways to call super class methods (including the constructor), however in Python-3.x the process has been simplified:

Python-2.x

class A(object): def __init__(self):   print "world"class B(A): def __init__(self):   print "hello"   super(B, self).__init__()

Python-3.x

class A(object): def __init__(self):   print("world")class B(A): def __init__(self):   print("hello")   super().__init__()

super() is now equivalent to super(<containing classname>, self) as per the docs.


super() returns a parent-like object in new-style classes:

class A(object):    def __init__(self):        print("world")class B(A):    def __init__(self):        print("hello")        super(B, self).__init__()B()


With Python 2.x old-style classes it would be this:

class A:  def __init__(self):    print "world" class B(A):  def __init__(self):    print "hello"    A.__init__(self)
