I wrote the following code. When I try to run it as at the end of the file I get this stacktrace: AttributeError: ''super'' object has no attribute do_something class Parent: def __init__(self):...
super() lets you avoid referring to the base class explicitly, which can be nice. But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen.
A diretiva super, sem parênteses, permite ainda invocar métodos da classe que foi derivada através da seguinte syntax. super.metodo(); Isto é útil nos casos em que faças override
The implicit __class__ used by super does not exist at this point. Thus, referencing the superclass by the hardcoded name, as one had to do prior to super in Python2 will work - and is the
