Moreover, any attempt to access attributes or items of None values is rendered as an empty string as well, instead of raising an exception. <br /> E.g. fmt.format('{a}{}{a[0]}', a=None) == ''</p> <p>This is useful e.g. when filling a template with values that are fetched from a DB, where usually None means empty.</p>
