particular, you can directly use <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> for your advanced concurrency use cases that require more advanced patterns in your own code.

And even if you were not using FastAPI, you could also write your own async applications with <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> to be highly compatible and get its benefits (e.g. *structured concurrency*)....

	// This function transforms the sparse format 0.0 headers into format 0.1
	// headers since 0.0 headers were not PAX compliant.
	var sparseMap []string

* Erstellen Sie eine `main.py`-Datei mit:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}

   * <p><b>Note:</b> this method simply delegates to the JDK method {@link Double#compare}. It is
   * provided for consistency with the other primitive types, whose compare methods were not added
   * to the JDK until JDK 7.
   *
   * @param a the first {@code double} to compare
   * @param b the second {@code double} to compare

* Create a `main.py` file with:

```Python

## 執行程式

在啟用虛擬環境後，你可以執行你的程式，它將使用虛擬環境中的 Python 和你在其中安裝的套件。

<div class="termy">

```console
$ python main.py

Hello World
```

</div>

## 設定編輯器

你可能會用到編輯器，請確保設定它使用你建立的相同虛擬環境（它可能會自動偵測到），以便你可以獲得自動完成和内嵌錯誤提示。

例如：

		// The method set has unexported methods, so all the
		// implementations are provided by the same package,
		// so the method set can be extended. Instead of recording
		// the full set of names (below), record only that there were
		// unexported methods. (If the interface shrinks, we will notice
		// because a method signature emitted during the last loop
		// will disappear.)
		w.emitf("unexported methods")
	}

	pop()

        return false;
      } else if (read1 != BUFFER_SIZE) {
        return true;
      }
    }
  }

  // The Arrays.equals(<arraytype>, int, int, <arraytype>, int, int) methods were not added until
  // Java 9. This function is just returns the same result that
  // Arrays.equals(array1, 0, count, array2, 0, count) would. It assumes that both arrays have a
  // length of at least count.
