All this might seem contrived. And it might not be very clear how is it useful yet.

These examples are intentionally simple, but show how it all works.

In the chapters about security, there are utility functions that are implemented in this same way.

If you understood all this, you already know how those utility tools for security work underneath.

	DateAdd   *DateAddFunc   `parser:"| @@"`
	DateDiff  *DateDiffFunc  `parser:"| @@"`

	// Used during evaluation for aggregation funcs
	aggregate *aggVal
}

// SimpleArgFunc represents functions with simple expression
// arguments.
type SimpleArgFunc struct {

    return new ToStringHelper(self.getClass().getSimpleName());
  }

  /**
   * Creates an instance of {@link ToStringHelper} in the same manner as {@link
   * #toStringHelper(Object)}, but using the simple name of {@code clazz} instead of using an
   * instance's {@link Object#getClass()}.
   *
   * <p>Note that in GWT, class names are often obfuscated.
   *
   * @param clazz the {@link Class} of the instance

Sie haben gerade den Haupt-Einsatzort für die Deklaration von Typhinweisen gesehen. Als Funktionsparameter.

Das ist auch meistens, wie sie in **FastAPI** verwendet werden.

### Einfache Typen { #simple-types }

Sie können alle Standard-Python-Typen deklarieren, nicht nur `str`.

Zum Beispiel diese:

* `int`
* `float`
* `bool`
* `bytes`

Then we **assign those two values** of the tuple to the variables `id` and `name`.

So, if the user didn't provide an item ID, they will still receive a random suggestion.

...we do all this in a **single simple line**. 🤯 Don't you love Python? 🐍
