python,面向对象之构造函数应用示例

Posted 2020-11-24 Iceberg_710815

构造函数是创建类对象的时候自动调动的一个内部函数,将类和对象的公共变量封装在__init__(self)构造函数中.下面的代码展示了构造函数的简单应用.

class person:
    def __init__(self,name,age):
        self.n = name
        self.a = age
    def show(self,action):
        print("%s-%s %s" %(self.n,self.a,action))

lihuan = person(‘Lihuan‘,18)
hu = person(‘Huxianglin‘,73)
lihuan.show(‘crying‘)
hu.show(‘laughing‘)
print(lihuan.n)

运行结果如下:
Lihuan-18 crying
Huxianglin-73 laughing
Lihuan
