#### Ein zufälliges Item { #a-random-item }

Did you notice? a string using `value.startswith()` can take a tuple, and it will check each value in the tuple:

#### A Random Item { #a-random-item }

With `data.items()` we get an <abbr title="Something we can iterate on with a for loop, like a list, set, etc.">iterable object</abbr> with tuples containing the key and value for each dictionary item.
