Python type’larını nasıl kullanacağınıza dair 2 dakikalık bir hatırlatmaya ihtiyacınız varsa (FastAPI kullanmasanız bile) kısa eğitime göz atın: [Python Types](python-types.md).

Türleriyle standart Python yazarsınız:

```Python
from datetime import date

from pydantic import BaseModel

# Bir değişkeni str olarak belirt

You can configure where your app is located in a `pyproject.toml` file like:

```toml
[tool.fastapi]
entrypoint = "main:app"
```

That `entrypoint` will tell the `fastapi` command that it should import the app like:

```python
from main import app
```

If your code was structured like:

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

- そのため、画像・動画・大きなバイナリなどの大きなファイルでも、メモリを使い果たすことなくうまく動作します。
- アップロードされたファイルからメタデータを取得できます。
- [file-like](https://docs.python.org/3/glossary.html#term-file-like-object) な `async` インターフェースを持ちます。
- 実際の Python の [`SpooledTemporaryFile`](https://docs.python.org/3/library/tempfile.html#tempfile.SpooledTemporaryFile) オブジェクトを公開しており、file-like オブジェクトを期待する他のライブラリにそのまま渡せます。

### `UploadFile` { #uploadfile }

`UploadFile` には次の属性があります:

`secrets.compare_digest()` needs to take `bytes` or a `str` that only contains ASCII characters (the ones in English), this means it wouldn't work with characters like `á`, as in `Sebastián`.

To handle that, we first convert the `username` and `password` to `bytes` encoding them with UTF-8.

		return strconv.FormatUint(uint64(v), 10)
	case uint64:
		return strconv.FormatUint(v, 10)
	}
	return ""
}

const nestedRelationSplit = "__"

// NestedRelationName nested relationships like `Manager__Company`
func NestedRelationName(prefix, name string) string {
	return prefix + nestedRelationSplit + name
}

// SplitNestedRelationName Split nested relationships to `[]string{"Manager","Company"}`

<abbr title="too long; didn't read"><strong>TL;DR:</strong></abbr>

If you are using third party libraries that tell you to call them with `await`, like:

```Python
results = await some_library()
```

Then, declare your *path operation functions* with `async def` like:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

/// note

Let's start with an example and then see it in detail.

We create an async function `lifespan()` with `yield` like this:

{* ../../docs_src/events/tutorial003_py310.py hl[16,19] *}

the result.

## Running Microbenchmarks

Running via an IDE is not supported as the results are meaningless
because we have no control over the JVM running the benchmarks.

If you want to run a specific benchmark class like, say,
`MemoryStatsBenchmark`, you can use `--args`:

```
gradlew -p benchmarks run --args 'MemoryStatsBenchmark'
```

Everything in the `'` gets sent on the command line to JMH.
