Then, we can change the dependency "dependable" `common_parameters` from above to the class `CommonQueryParams`:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[11:15] *}

Pay attention to the `__init__` method used to create the instance of the class:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

...it has the same parameters as our previous `common_parameters`:
