Super () and __init__ () implementations are similar in the case of single inheritance Class Base (object): def __init__ (self): print ' base create ' class Childa (base): def __init__ (self): print ' creat A ', Base.__init__ (self) class Childb (Base): def __init__ (self): print ' creat B ', super (Childb, self). _ _init__ () base = Base () a = Childa () B = childb () Output results: B

Python advanced-MRO and super in succession Write in front If not specifically stated, the following are based on Python3 SummaryThis article describes Python how an inheritance relationship can be super() returned by calling the "parent class" method, super(Type, CurrentClass) returning the proxy for the CurrentClass MRO Type next class, and how to des

This article mainly introduces the usage of the super keyword in Python. The example analyzes the function and related usage skills of the super keyword. If you need it, refer to the example in this article to describe the usage of the super keyword in Python. Share it with you for your reference. The specific analysis is as follows: In the method of a Python cl

the concept of image resolution Image resolution refers to the imaging or display system to the details of the resolution, representing the amount of information stored in the image.The amount of information stored in an image is the number of pixels per inch of the image, and the resolution is measured in PPI (Pixels per inch), usually called pixels per inch.The size of the image is determined by the number of pixels, the resolution is the unit density, the higher the resolution of the same pi

Go to: https://mozillazg.com/2016/12/python-super-is-not-as-simple-as-you-thought.htmlWhen it comes to super, you may find it simple, not just to call the parent method. If it is so simple, then there will not be this article, and listen to me carefully. ConventionsBefore you begin, let's make an appointment with the Python version that this article uses. The default is Python 3, which means that the classe

Example Analysis of super keyword usage in Python and python instance analysis This example describes the usage of the super keyword in Python. Share it with you for your reference. The specific analysis is as follows: In the method of a Python class, to call a method of the parent class, before Python 2.2, the usual method is as follows: Code Segment 1: class A:def __init__(self): print "enter A" print "

This example describes the Super keyword usage in python. Share to everyone for your reference. The specific analysis is as follows: In the Python class method, you call a method of the parent class, which, before Python 2.2, is typically written like code Snippet 1: Code Snippet 1: ? 1 2 3 4, 5 6 7 8 9 10 11 12 13 14 15 Class A:def __init__ (self): print "Enter a" print "Leave A" class B (a): Def __init__ (self): print "Enter B" a

About the difference between self and super,The first thing to know about 1 is what self is and what super is. What 2,[Super init] does. 3, why should self = [super init];What is 1,self and what is super?> In dynamic methods, self represents an "object"> In static methods, s

Super keywordIn a subclass that represents a reference to a parent class object, you can call the properties of a method in the parent class in a subclass.Super Statement---Subclass after inheriting the parent class, the child class will have a super statement in its construction method.If the super statement is not manually specified, the parent class is called

1. How to use SuperWhen I started to use super with the example code, I thought it was simple, just like the super in the language of other single-inheritance mechanisms. However, when you try to mix things like bound Super object, with Unbound super Object,metaclass,proxy Object,descriptor,mro,multiple inheritance Thi

1. Subclass constructors If you want to refer to super, you must put super in the first place of the function.class Base {Base () {System. out. println ("Base");}} Publicclass Checket extends Base {Checket () {Super ();//Call the constructor of the parent class, be sure to put it in the first statement of the methodSystem. out. println ("Checket");} PublicStatic

Class A:def __init__ (self):Print "Enter A"Print "Leave A"Class B (A):def __init__ (self):Print "Enter B"a.__init__ (self) # old methodPrint "Leave B">>> B = B ()Enter BEnter ALeave ALeave BThe disadvantage of this is that when the parent class of a subclass changes (such as when the parent class of Class B changes from A to C), the entire class definition must be traversed, replacing all the class names of the unbound methods.Since Python 2.2, Python has added a keyword

Python super I. Problem Discovery and Proposal In the method of a Python class, to call a method of the parent class, before Python 2.2, the usual method is as follows: Code Segment 1: Class:Def _ init _ (self ):Print "enter"Print "leave" Class B ():Def _ init _ (self ):Print "enter B"A. _ init _ (self)Print "leave B" >>> B = B () Enter BEnterLeaveLeave B That is, use non-bound class methods (Methods referenced by class names), and introduce the objec

Python 2.2, Python has added a keyword "super" to solve this problem. The official documentation for python 2.3 is as follows: Super (type [, object-or-type]) Return the superclass of type. If the second argument is omitted the super objectReturned is unbound. If the second argument is an object, isinstance (OBJ, type)Must be true. If the second argument is a ty

We already know that if a member variable defined in a subclass has the same name as a member variable in the parent class, the member variable in the parent class cannot be inherited, and the member variable of the child class is called the member variable of the parent class is hidden.When a method is defined in a subclass, and the method's name, return type, number of arguments, and a method of the parent class are exactly the same, this method of the parent class is hidden (rewritten), neith

Python: super Getting started with super () In class inheritance, If you redefine a method, this method will overwrite the method of the same name as the parent class, but sometimes we want to implement the function of the parent class at the same time, we need to call the method of the parent class, which can be implemented by using super, for example: Class Ani
