python super() 用法与注意事项

Question

实例：

#! -*- encoding:utf-8 -*-

class People(object):

    def __init__(self, name ='haha', age = 0):
        self.name = name
        self.age = age

    def setName(self, name):
        self.name = name
        return self

    def __setAge(self, age):
        self.age = age
        return self

    def getName(self):
        return self.name

    def getAge(self):
        return self.age

    setAge = __setAge

class Man(People):
    def __init__(self, name = '', age = 0):
        super(Man, self).__init__(name, age)

    def setSex(self, sex):
        self.sex = sex
        return self

    def getSex(self):
        return self.sex

a = People('Kevin')
print(a.name)
print(a.getAge())
name = a.setName('Kevin').setAge(22).getAge()
print(name)

b = Man('tom', 28)
print(b.name)

print(b.setSex('male').getSex())

python 2.7.6

错误：TypeError: must be type, not classobj

因为在父类中没有使用

class Base(object): 
    def __init__():

省略了 object 就会报错。

注意： super() 中的参数是如何调用的

super 还可以使用如下语法替代：

def __init__(self, name = '', age = 0):
        super(type(self), self).__init__(name, age)

或者：

def __init__(self, name = '', age = 0):
        super(self.__class__, self).__init__(name, age)
