是否可以用两种不同的方式实例化一个类的对象? [英] Is it possible to instantiate an object of one class in two different ways?

问题描述

此处是创建点的示例作为p=Point(x, y).假设我有一些数组ppp=(x, y)，其中x和y是数字，我想将其设置为类Point，但方式是:p=Point(ppp).我可以采用一种或另一种方式，但不能同时进行.可以同时有两种方法吗?

Here is an example which creates a point as p=Point(x, y). Assume that I have some array ppp=(x, y) where x and y are numbers and I want to make it of class Point but in the way: p=Point(ppp). I can do either one or another way but not both simultaneously. Is it possible to have both ways?

推荐答案

如果您知道在创建实例时拥有一个元组/列表，则可以执行:p = Point(*ppp)，其中是元组.

If you know that you have a tuple/list while creating the instance, you can do: p = Point(*ppp), where ppp is the tuple.
