Super() lets you avoid referring to the base class explicitly, which can be nice Within each class there is a print But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen.

Super() is a special use of the super keyword where you call a parameterless parent constructor For example, i have a class called parent, and a class called child which is derived from parent In general, the super keyword can be used to call overridden methods, access hidden fields or invoke a superclass's constructor.
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. The one with super has greater flexibility The call chain for the methods can be intercepted and functionality injected. 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 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
'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. Now i want to test the childrunner() method of childclass and since this method internally calls the super class method, i need some help/piece of code on how to mock the run() method which is present in superclass.
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 How do i call the parent function from a derived class using c++
