FastAPI converts the configurations to **JSON** to make them compatible with JavaScript, as that's what Swagger UI needs.

## Disable Syntax Highlighting

For example, you could disable syntax highlighting in Swagger UI.

Without changing the settings, syntax highlighting is enabled by default:

<img src="/img/tutorial/extending-openapi/image02.png">

But you can disable it by setting `syntaxHighlight` to `False`:

	cmd := &cobra.Command{
		Use:   "prometheus",
		Short: "Open Prometheus web UI",
		Long:  `Open Istio's Prometheus dashboard`,
		Example: `  istioctl dashboard prometheus

  # with short syntax
  istioctl dash prometheus
  istioctl d prometheus`,
		RunE: func(cmd *cobra.Command, args []string) error {
			client, err := ctx.CLIClientWithRevision(opts.Revision)
			if err != nil {

     * @param context The environmental context used to determine the activation status of the profile, must not be
     *            {@code null}.
     * @param problems The container used to collect problems (e.g. bad syntax) that were encountered, must not be
     *            {@code null}.
     * @return {@code true} if the profile is active, {@code false} otherwise.
     */

     *
     * @param version the version string to parse, must not be {@code null}
     * @return the parsed version, never {@code null}
     * @throws VersionParserException if the string violates the syntax rules of this scheme
     */
    @Nonnull
    Version parseVersion(@Nonnull String version);

    /**
     * Parses the specified version range specification, for example "[1.0,2.0)".
     *

#### Liste

Definieren wir zum Beispiel eine Variable, die eine `list` von `str` – eine Liste von Strings – sein soll.

=== "Python 3.9+"

    Deklarieren Sie die Variable mit der gleichen Doppelpunkt-Syntax (`:`).

    Als Typ nehmen Sie `list`.

name can appear multiple times the returned Values can contain
more than one value for a given key.

The new [ParseSetCookie] function parses a Set-Cookie header value and

If you can use the **latest versions of Python**, use the examples for the latest version, those will have the **best and simplest syntax**, for example, "**Python 3.10+**".

#### List

For example, let's define a variable to be a `list` of `str`.

=== "Python 3.9+"

    Declare the variable, with the same colon (`:`) syntax.

    As the type, put `list`.

### Sadece modern Python

Tamamiyle standartlar **Python 3.8**'nın type hintlerine dayanıyor (Pydantic'in sayesinde). Yeni bir syntax öğrenmene gerek yok. Sadece modern Python.
