Here s a breakdown of what this code does Line 3 defines the Point class using the class keyword followed by the class name Line 4 defines the new method which takes the class as its first argument Note that using cls as the name of this argument is a strong convention in Python just like using self to name the current instance is The method also takes args and kwargs which
PEP 487 Simpler customisation of class creation Python, Currently customising class creation requires the use of a custom metaclass This custom metaclass then persists for the entire lifecycle of the class creating the potential for spurious metaclass conflicts This PEP proposes to instead support a wide range of customisation scenarios through a new init subclass hook in the class body and

Python Class Constructor Examples Let s look at some examples of the constructor function in different scenarios 1 Class with No Constructor We can create a class without any constructor definition In this case the superclass constructor is called to initialize the instance of the class The object class is the base of all the classes Python Class Constructor Python init Function AskPython.
