# Pfad-Parameter und Validierung von Zahlen { #path-parameters-and-numeric-validations }

So wie Sie mit `Query` für Query-Parameter zusätzliche Validierungen und Metadaten deklarieren können, können Sie mit `Path` die gleichen Validierungen und Metadaten für Pfad-Parameter deklarieren.

## `Path` importieren { #import-path }

Importieren Sie zuerst `Path` von `fastapi`, und importieren Sie `Annotated`:

 * types, and also for interfaces and public classes that have public parameter-less constructors.
 * When the non-null default value for a particular parameter type cannot be provided by {@code
 * NullPointerTester}, the caller can provide a custom non-null default value for the parameter type
 * via {@link #setDefault}.

* The alternative documentation will also reflect the new query parameter and body:

### Recap { #recap }

In summary, you declare **once** the types of parameters, body, etc. as function parameters.

You do that with standard modern Python types.

# Header-Parameter { #header-parameters }

Sie können Header-Parameter genauso definieren, wie Sie `Query`-, `Path`- und `Cookie`-Parameter definieren.

## `Header` importieren { #import-header }

Importieren Sie zuerst `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## `Header`-Parameter deklarieren { #declare-header-parameters }

 * If this parameter is not present, an empty string is returned as the content.</p>
