python类的简单使用

class Person:
    def __init__(self, name , age):
        self.name = name
        self.age = age
    def print_name(self):
        print("my name is %s"%self.name)
    def print_age(self):
        print("my age is {}".format(self.age))

pTest = Person("Bob", "25")
print("这是类实例化后的内存地址：%s"%pTest)
pTest.print_name()
pTest.name = "Make"
pTest.print_age()
