FastAPI é um moderno e rápido (alta performance) _framework web_ para construção de APIs com Python, baseado nos _type hints_ padrões do Python.

Os recursos chave são:

* **Rápido**: alta performance, equivalente a **NodeJS** e **Go** (graças ao Starlette e Pydantic). [Um dos frameworks mais rápidos disponíveis](#performance).
* **Rápido para codar**: Aumenta a velocidade para desenvolver recursos entre 200% a 300%. *

   * Copies all mappings from the specified table to this table. The effect is equivalent to calling
   * {@link #put} with each row key / column key / value mapping in {@code table}.
   *
   * @param table the table to add to this table

/**
 * Manages a dictionary file for synonyms.
 * This class handles reading, parsing, and updating files that contain
 * synonym rules. The file format supports both explicit mappings (e.g., `a => b`)
 * and equivalent synonyms (e.g., `a, b, c`).
 *
 * The class provides methods for retrieving, adding, updating, and
 * deleting synonym items, as well as reloading the dictionary
 * from its source file.

 * degrades more gracefully for worst-case input.

 * <p>The implementation does not necessarily use a <i>stable</i> sorting algorithm; when multiple
 * equivalent elements are added to it, it is undefined which will come first in the output.

Mas se nós estamos construindo uma aplicação OAuth2 que outros poderiam conectar (i.e., se você está construindo um provedor de autenticação equivalente ao Facebook, Google, GitHub, etc.) você deveria utilizar um dos outros fluxos.

O mais comum é o fluxo implícito.

A sintaxe `{"name", "description"}` cria um `set` com esses dois valores.

É equivalente a `set(["name", "description"])`.
