) # A --> C Print "leave B" If the code is simple, such changes may be acceptable. However, if the code volume is large, such modifications may be disastrous. Change to super Super Example 1: Class Base (object ): Def _ Init __ (Self ): Print ( " Base created " ) Class Childa (base ): Def _ Init __ (Self): base. _ Init __ (Self) Class Childb (base ): Def _ Init __ (Self):

English documents:super([type[, object-or-type]]) Return a proxy object, delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that has been overridden in a class. The search order is same as, used by getattr() except, the type itself is skipped.The __mro__ attribute of the type lists the method resolution search order used by both getattr() and super() . The attribute is dynamic and can wheneve

This article mainly introduces the usage of super in Python. This article describes the discovery and proposal of super, the implementation of super in the source code world of Python, and the continuation of the discussion of super, for more information, see I. Problem Discovery and Proposal In the method of a Python

Class base {base () {system. out. println ("base") ;}} publicclass checketextends base {checket () {super (); // call the constructor of the parent class, which must be placed in th

2.2, Python has added a keyword super to solve this problem. The following is an official document description of Python 2.3: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 type,

amount of code is large, such a modification could be catastrophic. So, since Python 2.2, Python has added a keyword super to solve this problem. The following is an official document description of Python 2.3:Copy the Code code as follows: Super (type[, Object-or-type]) Return the superclass of type. If The second argument is omitted the Super objectReturned

A super user is the owner of the highest permissions of the system and the only winner of system management. a super user has super permissions and is omnipotent. if the super user is not good at management, it will pose a threat to system security. In addition to avoiding the direct use of

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

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 "

Python inheritance and invoking the parent class memberThe Python subclass calls the parent class member in 2 ways, namely the normal method and the Super methodSuppose base is a base classclass Base (object): def __init__ (self): Print "Base Init"The common method is as followsclass Leaf (Base): def __init__ (self): Base. __init__ (self) Print "Leaf Init"The S
