Python class and instance, Python class instance
The most important concepts of object-oriented are Class and Instance. You must remember that classes are abstract templates, such as Student classes, instances are specific "objects" created based on classes. Each object has
Python class instance method, class method, class static method,
The following class definition is used as an example:
# Coding: utf-8class A: count = 0 def _ init _ (self, inst_name): self. inst_name = inst_name self. _
Simply put, the meta-class creates all the objects in Python. We say that Python is a dynamic language, and the biggest difference between dynamic and static languages is that functions and classes are not defined at compile time, but are created dynamically at runtime.For example, if we want to define a HelloWorld
Take the following class definition as an example:# Coding:utf-8ClassA:Count=0Def__init__(Self,Inst_name):Self.Inst_name=Inst_nameSelf.__class__.Count+=1DefInst_method(Self):PrintInstance%s):%s‘%(Self.__class__.Count,Self.Inst_name)@classmethodDefClass_method(Cls):PrintCls.Count@staticmethodDefStatic_method():Print' Hello 'A1,a2,a3,a4 = a ( ' A1 ' a ( ' A2 ' a ( "A3" Span
