Il s'agissait de l'un des premiers exemples de **documentation automatique pour API**, et c'est précisément l'une des
premières idées qui a inspiré "la recherche de" **FastAPI**.

To see what gets put in the binary after linking, use <code>go tool objdump</code>:

$ go build -o x.exe x.go
$ go tool objdump -s main.main x.exe
TEXT main.main(SB) /tmp/x.go

# Bigger Applications - Multiple Files { #bigger-applications-multiple-files }

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

## Motivación

Comencemos con un ejemplo simple:

{* ../../docs_src/python_types/tutorial001.py *}

Llamar a este programa genera:

```
John Doe
```

La función hace lo siguiente:

* Toma un `first_name` y `last_name`.
* Convierte la primera letra de cada uno a mayúsculas con `title()`.
* <abbr title="Los une, como uno. Con el contenido de uno después del otro.">Concatena</abbr> ambos con un espacio en el medio.

### Beispieltools zum automatischen Neustart

In den meisten Fällen wird dasselbe Tool, das zum **Ausführen des Programms beim Hochfahren** verwendet wird, auch für automatische **Neustarts** verwendet.

Dies könnte zum Beispiel erledigt werden durch:

* Docker
* Kubernetes
* Docker Compose

    *   Added support for `tflite_convert` command line tool in 2.0.
    *   Post-training quantization tool supports quantizing weights shared by
        multiple operations. The models made with versions of this tool will use
        INT8 types for weights and will only be executable interpreters from
        this version onwards.
    *   Post-training quantization tool supports fp16 weights and GPU delegate

### Example Tools to Restart Automatically { #example-tools-to-restart-automatically }

In most cases, the same tool that is used to **run the program on startup** is also used to handle automatic **restarts**.

For example, this could be handled by:

* Docker
* Kubernetes
* Docker Compose
* Docker in Swarm Mode
* Systemd

* Tài liệu thay thế cũng sẽ phản ánh tham số và body mới:

### Tóm lại

Bạn khai báo **một lần** kiểu dữ liệu của các tham số, body, etc là các tham số của hàm số.

Bạn định nghĩa bằng cách sử dụng các kiểu dữ liệu chuẩn của Python.

## Metrics Request Handling

Each endpoint can be queried as needed via a scrape configuration in Prometheus or a compatible metrics collection tool. You should schedule scrape operations so a prior scrape completes before the next one begins.
