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
an instance method, which is called automatically when the instance is created. In this case, whenever an instance is initialized, it __class__ accesses the class attribute count, which is added to the count of instances of the class.def __init__(self, inst_name): self.inst_name = inst_name self.__class__.count += 1Class method: The first parameter is coerced to a class object, and the

Note: Here we only describe how to use the method. The concept of a specific class should not be difficult for me.
In a word, a programming language is just a tool and can be

New Writing of the Python abstract class and the writing of the Python abstract class
I remember in the previous book learn python, because there was no official support at the time, I could only use the hack method to implement the abstract method. The simplest method is as

It's not long enough to touch the Python language, and many of the features of the language are not well understood, and many usages are not yet known. Today I want to write a function call in the inheritance of Python object-oriented programming. Share it and make progress together.Because of previous exposure to Java and C + +, all of the ideas for object-oriented are already well-known. There is no longe
