class MyClass(BaseClass): def __new__(cls, *args, **kwargs): return super(MyClass, cls).__new__(cls, *args, **kwargs)
super并不是一个函数，而是一个类名，形如super(B, cls)事实上调用了super类的初始化函数，产生了一个super对象。Python Manuals上介绍：super(type[, object-or-type]) Return a proxy object that delegates method calls to a parent or sibling class of type. Note: super() only works for new-style classes.
super接收两个参数，两个参数的类型之间需要有继承关系，否则会报：TypeError: super(type, obj): obj must be an instance or subtype of type
T.__new__(S, ...) return a new object with type S, a subtype of T
