### Simplemente Python moderno

Todo está basado en las declaraciones de tipo de **Python 3.8** estándar (gracias a Pydantic). No necesitas aprender una sintaxis nueva, solo Python moderno.

### فقط پایتون مدرن

همه اینها برپایه type declaration های **پایتون ۳.۶** استاندارد (به لطف Pydantic) میباشند. سینتکس جدیدی درکار نیست. تنها پایتون مدرن استاندارد.

### Chỉ cần phiên bản Python hiện đại

Tất cả được dựa trên khai báo kiểu dữ liệu chuẩn của **Python 3.8** (cảm ơn Pydantic). Bạn không cần học cú pháp mới, chỉ cần biết chuẩn Python hiện đại.

### 更主流的 Python

全部都基于标准的 **Python 3.6 类型**声明（感谢 Pydantic ）。没有新的语法需要学习。只需要标准的 Python 。

如果你需要2分钟来学习如何使用 Python 类型（即使你不使用 FastAPI ），看看这个简短的教程：[Python Types](python-types.md){.internal-link target=_blank}。

Then at some point, it finally is your turn. You go to the counter, get your burgers and come back to the table.

Al final, en algún momento, llega tu turno. Vas al mostrador, coges tus hamburguesas 🍔 y vuelves a la mesa.

Tú y esa persona 😍 se comen las hamburguesas 🍔 y la pasan genial ✨.

Dann, irgendwann, sind Sie endlich an der Reihe. Sie gehen zur Theke, holen sich die Burger und kommen zurück an den Tisch.

Sie und Ihr Schwarm essen die Burger und haben eine schöne Zeit. ✨
