Super Bowl Xxiii Confidential Content Additions #820

The one with super has greater flexibility The call chain for the methods can be intercepted and functionality injected. 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 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. 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(b, cls).do_your_stuff() causes a 's do_your_stuff method to be called with cls passed as the first argument In order for that to work, a 's do_your_stuff has to be a class method The linked page doesn't mention that, but that is definitively the case. What is the difference between the keywords this and super Both are used to access constructors of class right Can any of you explain?
