- 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
- What is a difference between lt;? super E gt; and lt;? extends E gt;?
super: List<? super T> 'super' guarantees object to be ADDED to the collection is of type T extends: List<? extends T> 'extend' guarantees object READ from collection is of type T Explanation: There are three things that need to be considered while understanding a difference between 'super' and 'extends' from type safety point of view 1
- 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
- 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
- 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!
- 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)
- correct way to use super (argument passing) - Stack Overflow
So I was following Python's Super Considered Harmful, and went to test out his examples However, Example 1-3, which is supposed to show the correct way of calling super when handling __init__ methods that expect different arguments, flat-out doesn't work
- Difference between a parent class and super class
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
