在Python中给定一个实例创建一个新的Class实例

Question

In Python, if I have an object, say x , then how do I create a new object y so that x and y are of the same class?

In Java, the code I want would look something like this:

Object y = x.getClass().newInstance();

Answer 1

You could probably do something like:

y = x.__class__()

or

y = type(x)()  #New style classes only

And, if you're wondering how to make a new style class, all you need to do is inherit from object (or use python 3.x)

Answer 2

几乎和Java一样：

y = x.__class__()
