Python Classes and objects

Objects are composed of methods and properties

The characteristics of an object are called properties

The behavior of an object is called a method

Named objects

class Bian3:     def aaa (Self,num):        self.num=num    def  bbb (self):        Print( " the number entered is%d " % self.num)

>>> a=bian3 ()
>>> A.AAA (2)
>>> a.bbb ()
The number entered is 2.

Here are two more examples:

classBian:def __init__(self,name): Self.name=namedefsss (self):Print('My name is%s, hello.'%self.name) #注意__init__ () method when calling a class, you can add parameters directly to the instantiation of the class, and then call the SSS () function directlyclassBian2:defSetName (self,name): Self.name=namedefddd (self):Print('My name is%s, hello.'% self.name)
