Python-super()函数

class FooParent(object):
    def __init__(self):
        self.parent = 'I\'m the parent.'
        print ('Parent')
    
    def bar(self,message):
        print ("%s from Parent" % message)
 
class FooChild(FooParent):
    def __init__(self):
        # super(FooChild,self) 首先找到 FooChild 的父类(就是类 FooParent),然后把类B的对象 FooChild 转换为类 FooParent 的对象
        super(FooChild,self).__init__()    
        print ('Child')
        
    def bar(self,message):
        super(FooChild, self).bar(message)
        print ('Child bar fuction')
        print (self.parent)
 
if __name__ == '__main__':
    fooChild = FooChild()
    fooChild.bar('HelloWorld')

 

执行结果:

Parent
Child
HelloWorld from Parent
Child bar fuction
I'm the parent.
