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

## Disable Syntax Highlighting { #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">

 * pattern syntax, which is compatible with the behavior of Maven 3 plugins like
 * maven-compiler-plugin and maven-clean-plugin.
 * <p>
 * Pattern syntax supports:
 * <ul>
 *   <li>Standard glob patterns with {@code *}, {@code ?}, and {@code **} wildcards</li>
 *   <li>Explicit syntax prefixes like {@code "glob:"} or {@code "regex:"}</li>

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 { #list }

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

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

As the type, put `list`.

As the list is a type that contains some internal types, you put them in square brackets:

boolean isDeployedBranch() {
  return env.BRANCH_NAME == 'master' || env.BRANCH_NAME == 'maven-4.0.x' || env.BRANCH_NAME == 'maven-3.9.x'
}

/**
 * To other developers, if you are using this method above, please use the following syntax.
 * By default this method does NOT execute ITs anymore, just "install".
 *
 * mavenBuild("<jdk>", "<profiles> <goals> <plugins> <properties>"
 *
 * @param jdk the jdk tool name (in jenkins) to use for this build

	}
	return path.Join(append([]string{etcdPathSeparator + prefix + etcdPathSeparator}, l...)...)
}

// dnsJoin joins labels to form a fully qualified domain name. If the last label is
// the root label it is ignored. Not other syntax checks are performed.
func dnsJoin(labels ...string) string {
	if len(labels) == 0 {
		return ""
	}
	ll := len(labels)
	if labels[ll-1] == "." {
		return strings.Join(labels[:ll-1], ".") + "."
	}

#### Liste { #list }

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

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

Als Typ nehmen Sie `list`.

					goto next
				}
			}
			if tok == scanner.EOF {
				p.errorf("unexpected EOF")
				return "", "", nil, false
			}
			// Split operands on comma. Also, the old syntax on x86 for a "register pair"
			// was AX:DX, for which the new syntax is DX, AX. Note the reordering.
			if tok == '\n' || tok == ';' || (nesting == 0 && (tok == ',' || tok == ':')) {
				if tok == ':' {

			case ')':
				tok = in.Stack.Next() // First token of macro definition.
				break Loop
			case ',':
				if acceptArg {
					in.Error("bad syntax in definition for macro:", name)
				}
				acceptArg = true
			case scanner.Ident:
				if !acceptArg {
					in.Error("bad syntax in definition for macro:", name)
				}
				arg := in.Stack.Text()
				if slices.Contains(args, arg) {

pass the internal type(s) as "type parameters" using square brackets: `[` and `]`

```Python
my_list: list[str]
```

That's all standard Python syntax for type declarations.

Use that same standard syntax for model attributes with internal types.

So, in our example, we can make `tags` be specifically a "list of strings":

{* ../../docs_src/body_nested_models/tutorial002_py310.py hl[12] *}

FastAPI konvertiert die Konfigurationen nach **JSON**, um diese mit JavaScript kompatibel zu machen, da die Swagger-Oberfläche das benötigt.

## Syntaxhervorhebung deaktivieren { #disable-syntax-highlighting }

Sie könnten beispielsweise die Syntaxhervorhebung in der Swagger-Oberfläche deaktivieren.

Ohne Änderung der Einstellungen ist die Syntaxhervorhebung standardmäßig aktiviert:
