The understanding of the self and class in Python

In order to clarify what self is, we first need to understand the relationship between instances and classes.

People are a type of people. People have attributes such as name, height, and weight. These attributes are different for different people. In addition, people have many methods (functions), such as thinking, running, sleeping, etc..

class Person:def __init__(self, name):self.name = name # define the properties of the classdef think(self): # self is actually an ordinary parameter of the class function think, which represents the called object, and the specific value of the parameter is our instance objectprint("{} is thinking".format(self.name))

Specific to each person, such as yourself, each specific person around you is an instance object of "human".Instances inherit all properties and methods of the class, for example:

xiaoming = Person("xiaoming")

We constructed a person called "xiaoming", which is an instance object of the Person class. We define a think method for the Person class, but it needs a parameter. We can pass the instance object of xiaoming.

>>>Person.think(xiaoming)xiaoming is thinking

So, the self here is actually just an ordinary parameter of the class function think, which represents the called object, and the specific value is our instance object, so why is it called self?In fact, this is a convention.
