/// note | Technical Details

When you import `Query`, `Path` and others from `fastapi`, they are actually functions.

That when called, return instances of classes of the same name.

So, you import `Query`, which is a function. And when you call it, it returns an instance of a class also named `Query`.

These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.

    private List<Crawler> crawlerList;

     * Initializes a new instance with default settings.

 *       clearly insufficient to hold all hash code values, this API represents a hash code as an
 *       instance of {@link HashCode}.
 *   <li><b>pure function:</b> the value produced must depend only on the input bytes, in the order
 *       they appear. Input data is never modified. {@link HashFunction} instances should always be
 *       stateless, and therefore thread-safe.

### Adım 2: bir `FastAPI` "instance"ı oluşturun { #step-2-create-a-fastapi-instance }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[3] *}

Burada `app` değişkeni `FastAPI` class'ının bir "instance"ı olacaktır.

Bu, tüm API'nızı oluşturmak için ana etkileşim noktası olacaktır.
