Super() is a special use of the super keyword where you call a parameterless parent constructor

In general, the super keyword can be used to call overridden methods, access hidden fields or invoke a superclass's constructor. The one with super has greater flexibility The call chain for the methods can be intercepted and functionality injected. 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

Isto é útil nos casos em que faças override (sobrescrevas) um método da classe pai e desejas invocar o método original. In fact, multiple inheritance is the only case where super() is of any use I would not recommend using it with classes using linear inheritance, where it's just useless overhead. I'm currently learning about class inheritance in my java course and i don't understand when to use the super() call I found this example of code where super.variable is used As for chaining super::super, as i mentionned in the question, i have still to find an interesting use to that

For now, i only see it as a hack, but it was worth mentioning, if only for the differences with java (where you can't chain super).

173 python also has super as well This is useful for accessing inherited methods that have been overridden in a class The search order is same as that used by getattr () except that the type itself is skipped 'super' object has no attribute '__sklearn_tags__' This occurs when i invoke the fit method on the randomizedsearchcv object I attempted to tune the hyperparameters of an xgbregressor.

I wrote the following code When i try to run it as at the end of the file i get this stacktrace 'super' object has no attribute do_something class parent
