## Tạo một Môi trường ảo

Khi bạn bắt đầu làm việc với một dự án Python **trong lần đầu**, hãy tạo một môi trường ảo **<abbr title="có nhiều cách thực hiện khác nhau, đây là một hướng dẫn đơn giản">trong thư mục dự án của bạn</abbr>**.

/// tip

Bạn cần làm điều này **một lần cho mỗi dự án**, không phải mỗi khi bạn làm việc.

## An app with callbacks { #an-app-with-callbacks }

Let's see all this with an example.

Imagine you develop an app that allows creating invoices.

These invoices will have an `id`, `title` (optional), `customer`, and `total`.

The user of your API (an external developer) will create an invoice in your API with a POST request.

Then your API will (let's imagine):

    protected final boolean includeObject;
