合并对象时如何在 object 创建中使用接口

Question

I have a issue im trying to create a new object with a new ID in an existing object but retain the model for the new object

Ive tried all methods of trying to get a decent simple way to do this and the way ive achieved it seems awfully wasteful

  addWindow() {
    let id = 0;

    for (const key in this.windowList) {
      if (parseInt(key, 10) >= id) {
        id = parseInt(key, 10);
      }
    }
    id++;

    const windowItem: WindowModel = {
      id,
      titleBar: 'Test Window ' + id
    };
    const item = {};
    item[id] = windowItem;
    this.windowList = {...this.windowList, ...item};

  }

and my interface is, as for now

export interface WindowModel {
    id: number;
    titleBar?: string;
}

What I want is to create a new item with the interface, that is then merged with the old object but retails the model scope.

Answer 1

You make something with javascript. Python is not needed fort this.

But here is the answer:

// finding for 2

  numbers = [1,2,3,0,4,5]
sum = 0
for number in numbers:
  if number = 0:
    print("non zero is" + number)
    sum = sum + numbers
print sum

Hope this helps!

Output: 3

The output is 3 which is correct
