Wir ändern den folgenden Teil, die Parameter der Funktion, von:

```Python
    first_name, last_name
```

zu:

```Python
    first_name: str, last_name: str
```

Das war's.

Das sind die „Typhinweise“:

{* ../../docs_src/python_types/tutorial002_py39.py hl[1] *}

Das ist nicht das gleiche wie das Deklarieren von Defaultwerten, wie es hier der Fall ist:

```Python

            try (InputStream inputStream = form.protwordsFile.getInputStream()) {
                file.update(inputStream);
            } catch (final IOException e) {
                logger.warn("Failed to process a request.", e);
                throwValidationError(messages -> messages.addErrorsFailedToUploadProtwordsFile(GLOBAL),
                        () -> redirectWith(getClass(), moreUrl("uploadpage/" + form.dictId)));

	return pCfg.ClaimPrefix + pCfg.ClaimName
}

// LookupUser lookup userid for the provider
func (r Config) LookupUser(roleArn, userid string) (provider.User, error) {
	// Can safely ignore error here as empty or invalid ARNs will not be
	// mapped.
	arnVal, _ := arn.Parse(roleArn)
	pCfg, ok := r.arnProviderCfgsMap[arnVal]
	if ok {
		user, err := pCfg.provider.LookupUser(userid)
		if err != nil && err != provider.ErrAccessTokenExpired {
