How to call class method in python

Classes in python are used to describe a collection of objects with the same properties and methods. It defines the properties and methods common to every object in the collection. Objects are instances of classes.

If you want to call a method in a class, you must first define a class. To define a class in python, use the class keyword

class Person():
    def __init__(self,name,age):#__init__()方法为类的构造方法
        self.name = name 
        self.age = age
    def detail(self):(通过self调用被封装的内容)
        print(self.name)
        print(self.age)
obj1 = Person('santos',18)
obj1.detail() #python将obj1传给self参数

There are two ways for python to call methods in a class: direct call through an object and indirect calls via self.
