super() is a special use of the super keyword where you call a parameterless parent constructor. In general, the super keyword can be used to call overridden methods, access hidden fields or invoke a superclass's constructor. The one without super hard-codes its parent's method - thus is has restricted the behavior of its method, and subclasses cannot inject functionality in the call chain.
The one with super has greater flexibility. The call chain for the methods can be intercepted and functionality injected. 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.
super 8 shreveport, 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? Edit: I found this example of code where super.variable is used: class A { ... Thirdly, when you call super() you do not need to specify what the super is, as that is inherent in the class definition for Child.
super 8 shreveport, Below is a fixed version of your code which should perform as you expect. 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__ met... 30 In Python-3.x you generally don't need the arguments for super anymore. That's because they are inserted magically (see PEP 3135 -- New Super). The two argument call and the no-argument call are identical if: The first argument is the class in which the method (that uses super) is defined.
In your case it's Ball so the condition is satisfied.
