`dict`, `list`, 단일값을 가진 `str`, `int` 등을 반환할 수 있습니다.

Pydantic 모델을 반환할 수도 있습니다(나중에 더 자세히 살펴봅니다).

JSON으로 자동 변환되는 객체들과 모델들(ORM 등을 포함해서)이 많이 있습니다. 가장 마음에 드는 것을 사용하십시오, 이미 지원되고 있을 것입니다.

## 요약

* `FastAPI` 임포트.
* `app` 인스턴스 생성.
* (`@app.get("/")`처럼) **경로 작동 데코레이터** 작성.
* (위에 있는 `def root(): ...`처럼) **경로 작동 함수** 작성.

Including external libraries also based on Pydantic, as <abbr title="Object-Relational Mapper">ORM</abbr>s, <abbr title="Object-Document Mapper">ODM</abbr>s for databases.

This also means that in many cases you can pass the same object you get from a request **directly to the database**, as everything is validated automatically.

Wliczając w to zewnętrzne biblioteki, również oparte o Pydantic, takie jak <abbr title="Mapowanie obiektowo-relacyjne. Po angielsku: Object-Relational Mapper">ORM</abbr>, <abbr title="Object-Document Mapper">ODM</abbr> dla baz danych.

Bunlara Pydantic üzerine kurulu <abbr title="Object-Relational Mapper">ORM</abbr> databaseler ve , <abbr title="Object-Document Mapper">ODM</abbr> kütüphaneler de dahil olmak üzere.

Inclusief externe pakketten die ook gebaseerd zijn op Pydantic, zoals <abbr title="Object-Relational Mapper">ORM</abbr>s, <abbr title="Object-Document Mapper">ODM</abbr>s voor databases.

	arg2, arg3 := e.From, e.For
	// Check if the second form of substring is being used
	if e.From == nil {

	}

Mas `OAuth2PasswordRequestForm` é apenas uma dependência de classe que você mesmo poderia ter escrito ou poderia ter declarado os parâmetros do `Form` (formulário) diretamente.

Mas como é um caso de uso comum, ele é fornecido diretamente pelo **FastAPI**, apenas para facilitar.
