python类属性的内存分析

class Student:
    classname = "Twenty"    # 类属性
    teachername = "JueJing"  # 类属性
    count = 0  # 类属性
 
    def __init__(self,name,age): #实例属性
        self.name = name
        self.age = age
 
    def information(self):
        print("{0} ".format(Student.classname))  # 调用类属性
        print("{0} age is {1}".format(self.name,self.age)) #调用实例属性
 
s1 = Student("Tome",19)
s1.information()
