How to invoke the super constructor in Python?

Question

class A:
    def __init__(self):
        print(\"world\")

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

B()  # output: hello

In all

Answer 1

Just to add an example with parameters:

class B(A):
    def __init__(self, x, y, z):
        A.__init__(self, x, y)

Given a derived class B that requires the variables x, y, z to be defined, and a superclass A that requires x, y to be defined, you can call the static method init of the superclass A with a reference to the current subclass instance (self) and then the list of expected arguments.
