 cleanup operations in a single :keyword:`with` statement. The variability
 may come from the number of context managers needed being driven by user
 input (such as opening a user specified collection of files), or from
 some of the context managers being optional::

 As shown, :class:`ExitStack` also makes it quite easy to use :keyword:`with`
 statements to manage arbitrary resources that don't natively support the
 context management protocol.
