super() in Java - Stack Overflow The super keyword can be used to call the superclass constructor and to refer to a member of the superclass When you call super() with the right arguments, we actually call the constructor Box, which initializes variables width, height and depth, referred to it by using the values of the corresponding parameters You only remains to initialize
oop - What does super do in Python? - Stack Overflow In Python 2, getting the arguments to super and the correct method arguments right can be a little confusing, so I suggest using the Python 3 only method of calling it If you know you're using super correctly with single inheritance, that makes debugging less difficult going forward Dependency Injection
Understanding Python super() with __init__() methods 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 See the standard docs on super if you haven't already It's rather hand-wavey and doesn't tell us much, but the point of super is not to avoid writing the parent
How does Pythons super () work with multiple inheritance? And call to super in that routine invokes init defined in First MRO=[First, Second] Now call to super in init defined in First will continue searching MRO and find init defined in Second, and any call to super will hit the default object init I hope this example clarifies the concept If you don't call super from First
python - replace block within { { super () }} - Stack Overflow 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
AttributeError: super object has no attribute - Stack Overflow @JuanR: I'm not sure when you'd be using super without it being inside of the class The no-argument version only works in that context If you're calling super on some other object, the two argument version works, but it's usually not a good idea to be bypassing the class's own methods in the first place –
java - When do I use super ()? - Stack Overflow That's because if you omit a call to the super constructor, the no-argument super constructor will be invoked automatically anyway Not to say that it's bad style; some people like being explicit However, where it becomes useful is when the super constructor takes arguments that you want to pass in from the subclass
How do I call a parent classs method from a child class in Python? super is only needed for proper support of multiple inheritance (and then it only works if every class uses it properly) In general, AnyClass whatever is going to look up whatever in AnyClass 's ancestors if AnyClass doesn't define override it, and this holds true for "child class calling parent's method" as for any other occurrence!
Why is super used so much in PySide PyQt? - Stack Overflow It seems that super seems most helpful when you have inheritance diamonds, that it tends to resolve instances of multiple inheritance in a reasonable way Is super used a lot with PySide because there is a preponderance of cases of such diamonds that I will confront with more realistic complicated examples? [Edit: No: see my answer below ]
python - Using super with a class method - Stack Overflow Since super(cls, cls) do_your_stuff() is called inside B do_your_stuff, you end up calling B do_your_stuff in an infinite loop In Python3, the 0-argument form of super was added so super(B, cls) could be replaced by super(), and Python3 will figure out from context that super() in the definition of class B should be equivalent to super(B, cls)
