objects, classes, and meta classes in Python __python

Uncle Turtle invented Python, and then integrated a bunch of concepts in the language, such as: iterators, adorners, Functions, generators, classes, objects, routines, and so on. These concepts do not seem to be a understood for beginners, but there is a more difficult concept, it is the creator of the Python world, although we rarely go directly to use it, but e

Deep mining of Python classes and meta-classes I "experience"

The previous article introduced the Python enumeration type of standard library, in addition to considering its usefulness, there is an important reason is that its implementation process is a very good learning, understanding the Python class and meta-class examples. So the next two articles take this as an example, digging deeper into the mechanics behind classes

Understanding and simple use of Python classes and meta-classes (Metaclass)

(i) Classes in PythonFirst, the Python classes discussed here are based on modern classes that inherit from object.First in Python, everything is an object. It's very important to understand the meta-class. I'm going to try to understand the

What is the inheritance of Python classes? What are the rules for inheriting classes?

Let's look at the inheritance of Python classes in this article, and for a friend who has just come into contact with Python's programming language, there should be less knowledge of the Python class's inheritance, but it's okay, in the next article we'll look at inheritance rules for Python

C and Python call one (import Python module with, get functions and classes)

pyrun_simplestring (s), the function of everyone to see what is used to do it. Using this function allows you to write some python directly in the parameters, and then the Python environment calls this function to complete the Python statement you wrote. For example pyrun_simplestring ("Import Tree"), using this statement, you can use

Single-Inheritance for Python classes and classes

Python is an object-oriented language, so OOP programming is a must.Below, I will summarize my study experience and learn knowledge.1. Declaration of a classClass Student (object):PassClass is the keyword that declares the class, and Student is the class name. In parentheses, object is used for inheritance, and if no other class is inherited, the object class is inherited.The pass area is the method and property of the classPrivate property or method:
