The call chain for the methods can be intercepted and functionality injected. The automatic insertion of super () by the compiler allows this 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.
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). '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 Super e>) says that it's some type which is an ancestor (superclass) of e Extends e>) says that it's some type which is a subclass of e
(in both cases e itself is okay.) so the constructor uses the Extends e form so it guarantees that when it fetches values from the collection, they will all be e or some subclass (i.e The super keyword is not specific to android It's a concept belonging to oop, and represents the parent class of the class in which you use it
In android, it's mostly usefull when you create your own activity or component, and lets you call a default behavior before implementing yours
For instance, the super methods must be called before anything when you override the activity onpause, on.
