I'm trying to understand the use of super() .

(我试图了解super()的用法。)

From the looks of it, both child classes can be created, just fine.

(从外观上看，两个子类都可以创建，就很好。)

I'm curious to know about the actual difference between the following 2 child classes.

(我很想知道以下两个子类之间的实际区别。)

class Base(object):
    def __init__(self):
        print "Base created"

class ChildA(Base):
    def __init__(self):
        Base.__init__(self)

class ChildB(Base):
    def __init__(self):
        super(ChildB, self).__init__()

ChildA() 
ChildB()

Answer 1

super() lets you avoid referring to the base class explicitly, which can be nice.

(super()可以避免显式引用基类，这可能很好。)

But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen.

(但是主要优势来自多重继承，其中可以发生各种有趣的事情。)

See the standard docs on super if you haven't already.

(如果还没有的话，请参阅关于super的标准文档 。)

Note that the syntax changed in Python 3.0 : you can just say super().__init__() instead of super(ChildB, self).__init__() which IMO is quite a bit nicer.

(请注意， Python 3.0中的语法已更改 ：您只能说super().__init__()而不是super(ChildB, self).__init__() ，这对IMO来说要好得多。)

The standard docs also refer to a guide to using super() which is quite explanatory.

(标准文档还参考了使用super()的指南，这是非常说明性的。)
