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%. *

**FastAPI** oferece uma ferramenta conveniente para estruturar sua aplicação, mantendo toda a flexibilidade.

Se você vem do Flask, isso seria o equivalente aos Blueprints do Flask.

## Um exemplo de estrutura de arquivos

Digamos que você tenha uma estrutura de arquivos como esta:

```
.
├── app
│   ├── __init__.py
│   ├── main.py

Within a parenthesized <code>const</code> declaration list the
expression list may be omitted from any but the first ConstSpec.
Such an empty list is equivalent to the textual substitution of the
first preceding non-empty expression list and its type if any.
Omitting the list of expressions is therefore equivalent to
repeating the previous list.  The number of identifiers must be equal
to the number of expressions in the previous list.

#### About `**user_dict`

`UserInDB(**user_dict)` means:

*Pass the keys and values of the `user_dict` directly as key-value arguments, equivalent to:*

```Python
UserInDB(
    username = user_dict["username"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    disabled = user_dict["disabled"],

			goldenConfig := testutils.ReadFile(t, goldenFilepath)
			testutils.CompareBytes(t, output, goldenConfig, goldenFilepath)
		})
	}
}

	// For testing purposes, set kubeconfigFilename equivalent to the path in the test files and use __KUBECONFIG_FILENAME__
	// CreateCNIConfigFile joins the MountedCNINetDir and KubeconfigFilename if __KUBECONFIG_FILEPATH__ was used
	kubeconfigFilename   = "/path/to/kubeconfig"

   * to be a separator. For example, {@code Splitter.onPattern("\r?\n").split(entireFile)} splits a
   * string into lines whether it uses DOS-style or UNIX-style line terminators. This is equivalent
   * to {@code Splitter.on(Pattern.compile(pattern))}.
   *
   * @param separatorPattern the pattern that determines whether a subsequence is a separator. This
   *     pattern may not match the empty string.
