+## Практика
+
+Задача: реализовать декоратор `@contract`. Смотри файл `contract.py`
+
+Требования:
+
+1. Необходимо проверять типы аргументов и тип выходного значения функции. Указываем кортеж типов для `arg_types`. Каждый тип в кортеже - соответсвует типу аргумента. Для типа выходного значения - указываем `return_type`
+
+```python
+@contract(arg_types=(int, int), return_type=int)
+def add_two_numbers(first, second):
+    return first + second
+
+add_two_numbers(1, 2)  # ok
+```
+
+2. Если передан неправильный тип, вызываем ошибку `ContractError`:
+
+```python
+add_two_numbers('a', 'b')  # raises ContractError
+```
+
+3. Параметр `raises` отвечает за типы исключений, которые функция может кидать. Если выкинутое исключение отсутсвует в списке разрешенных, то мы добавляем `ContractError` (смотри `raise from`). Пример:
+
+```python
+@contract(arg_types=(int, int), return_type=float, raises=(ZeroDivisionError,))
+def div(first, second):
+    return first / second
+
+div(1, 2)  # ok
+div(1, 0)  # raises ZeroDisionError
+div(1, None)  # raises ContractError from TypeError
+```
+
+4. Можно не передавать какое-то значение из `arg_types` или `return_type`. Или передать значение `None`: тогда ничего не будет происходить. Пример:
+
+```python
+# validates only return type, args and raises are ignored:
+@contract(return_type=int)
+
+# validation is completely disabled:
+@contract(return_type=None, arg_types=None, raises=None)
+
+# return type and raises checks are disabled:
+@contract(arg_types=(str, str))
+```
+
+5. Можно передать специальное значение `Any` для того, чтобы игнорировать какой-то один тип внутри `arg_types` или `raises`. Например:
+
+```python
+@contract(arg_types=(int, Any))
+def add_two_numbers(first, second):
+    return first + second
+
+add_two_numbers(1, 2)  # ok
+add_two_numbers(1, 3.4)  # ok
+add_two_numbers(2.1, 1)  # raises ContractError
+```
