## First dependency "dependable" { #first-dependency-dependable }

You could create a first dependency ("dependable") like:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

It declares an optional query parameter `q` as a `str`, and then it just returns it.

This is quite simple (not very useful), but will help us focus on how the sub-dependencies work.

Wenn Sie also Teil-Aktualisierungen empfangen wollen, die alle Attribute auslassen können, müssen Sie ein Modell haben, dessen Attribute alle als optional gekennzeichnet sind (mit Defaultwerten oder `None`).
