In general, the super keyword can be used to call overridden methods, access hidden fields or invoke a superclass's constructor. Fortunately for us, super works even with a type as the second argument 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.
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 the child template, i would like to include everything that was in the head block from the base (by calling { { super ()) }} and include some additional things, yet at the same time replace the title block within the super call. 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).
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 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
Super in generics is the opposite of extends Instead of saying the comparable's generic type has to be a subclass of t, it is saying it has to be a superclass of t The distinction is important because extends tells you what you can get out of a class (you get at least this, perhaps a subclass) Super tells you what you can put into the class (at most this, perhaps a superclass)
Super() is how the parent or super class constructor for a java class is invoked in a derived class There was a fair amount of churn in the terminology during the first years of object oriented programming as various people worked in the area and published papers and books and developed object oriented languages. If we're using a class method, we don't have an instance to call super with
