#### Unpacking a `dict` { #unpacking-a-dict }

If we take a `dict` like `user_dict` and pass it to a function (or class) with `**user_dict`, Python will "unpack" it. It will pass the keys and values of the `user_dict` directly as key-value arguments.

So, continuing with the `user_dict` from above, writing:

```Python
UserInDB(**user_dict)
```

would result in something equivalent to:

```Python
UserInDB(

        Secured secured = MultipleRolesClass.class.getAnnotation(Secured.class);
        String[] roles1 = secured.value();
        String[] roles2 = secured.value();

        // Different array instances should be returned
        assertNotSame(roles1, roles2);

        // But values should be the same
        assertEquals(roles1.length, roles2.length);
        for (int i = 0; i < roles1.length; i++) {

		return cred, ErrSignatureDoesNotMatch
	}
	return cred, ErrNone
}

// Escape encodedQuery string into unescaped list of query params, returns error
// if any while unescaping the values.
func unescapeQueries(encodedQuery string) (unescapedQueries []string, err error) {
	for query := range strings.SplitSeq(encodedQuery, "&") {
		var unescapedQuery string
		unescapedQuery, err = url.QueryUnescape(query)

    }
