### Clases como tipos

También puedes declarar una clase como el tipo de una variable.

Digamos que tienes una clase `Person`, con un nombre:

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}

Luego puedes declarar una variable para que sea de tipo `Person`:

{* ../../docs_src/python_types/tutorial010.py hl[6] *}

Y luego, nuevamente, obtienes todo el soporte del editor:

* `Optional`
* ...و بقیه.

////

### کلاس‌ها به‌عنوان نوع

می‌تونی یه کلاس رو هم به‌عنوان نوع یه متغیر تعریف کنی.

فرض کن یه کلاس `Person` داری، با یه نام:

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}

بعد می‌تونی یه متغیر رو از نوع `Person` تعریف کنی:

{* ../../docs_src/python_types/tutorial010.py hl[6] *}

و بعد، دوباره، همه پشتیبانی ویرایشگر رو داری:

### ক্লাস হিসেবে টাইপস

আপনি একটি ভেরিয়েবলের টাইপ হিসেবে একটি ক্লাস ঘোষণা করতে পারেন।

ধরুন আপনার কাছে `Person` নামে একটি ক্লাস আছে, যার একটি নাম আছে:

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}


তারপর আপনি একটি ভেরিয়েবলকে `Person` টাইপের হিসেবে ঘোষণা করতে পারেন:

{* ../../docs_src/python_types/tutorial010.py hl[6] *}


এবং তারপর, আবার, আপনি এডিটর সাপোর্ট পেয়ে যাবেন:

   * identical inputs: This sounds like it ought to be a problem here, since the goals of this class
   * include testing that {@code equals()} is reflexive and is tolerant of {@code null}. However,
   * there's no problem. The reason: {@link EqualsTester} tests {@code null} and identical inputs
   * directly against {@code equals()} rather than through the {@code Equivalence}.

  `You're wrong about the crumbs,' said the Mock Turtle:
`crumbs would all wash off in the sea.  But they HAVE their tails
in their mouths; and the reason is--' here the Mock Turtle
yawned and shut his eyes.--`Tell her about the reason and all
that,' he said to the Gryphon.

  `The reason is,' said the Gryphon, `that they WOULD go with
the lobsters to the dance.  So they got thrown out to sea.  So
