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

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,
Java Super keywordThe Super keyword is similar to this, this is used to represent an instance of the current class, and super is used to represent the parent class. Super can be used in subclasses, by Dot (.) To get the member variables and methods of the parent class. Super
Similarities and differences between Super and this: super (parameter): Call one of the constructors in the base class (which should be the first statement in the constructor) this (argument): Call another constructor in this class (which should be the first statement in the constructor) Super: It refers to members in the immediate parent class of the current obj
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

By defining a method or member with static, it provides some convenience for us to program, and to some extent it is similar to global functions and global variables in C language. However, it is not said that with this convenience, you can use everywhere, if so, you need to seriously consider whether you are using object-oriented thinking programming, whether your own program is object-oriented. OK, now let's discuss the meaning and usage of the two keywords Thissuper. In Java, this usually ref

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
defined for this purpose.static variablesStatic variables are similar to static methods. All such instances share this static variable, that is, when the class is loaded, only one storage space is allocated, and all objects of this class can manipulate this block of storage space, although for final it is a matter of course . Look at the following code:classvalue{Static intC=0;Static voidInc () {C++;}}classcount{ Public Static voidprt (String s) {System.out.println (s);} Public Static voidMain
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 "
