#### Про `**user_dict` { #about-user-dict }

`UserInDB(**user_dict)` означает:

*Передать ключи и значения `user_dict` непосредственно как аргументы ключ-значение, эквивалентно:*

The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:
