# İlk Adımlar

En sade FastAPI dosyası şu şekilde görünür:

{* ../../docs_src/first_steps/tutorial001.py *}

Yukarıdaki içeriği bir `main.py` dosyasına kopyalayalım.

Uygulamayı çalıştıralım:

<div class="termy">

```console
$ uvicorn main:app --reload

func (w *Writer) CreateHeader(fh *FileHeader) (io.Writer, error) {
	if err := w.prepare(fh); err != nil {
		return nil, err
	}

	// The ZIP format has a sad state of affairs regarding character encoding.
	// Officially, the name and comment fields are supposed to be encoded
	// in CP-437 (which is mostly compatible with ASCII), unless the UTF-8

        unmodifiable.iterator(), modifiable.iterator());
  }

  public void testInvertFrom() {
    ImmutableMultimap<Integer, String> empty = ImmutableMultimap.of();

    // typical usage example - sad that ArrayListMultimap.create() won't work
    Multimap<String, Integer> multimap =
        Multimaps.invertFrom(empty, ArrayListMultimap.<String, Integer>create());
    assertTrue(multimap.isEmpty());
