Yes.  Either as soon as the file object has no more
references to it (with CPython), or as soon as the
application terminates or the garbage collection
executes to reclaim the objects (Jython, IronPython,
and any other Pythons that don't use reference
counting).

Either way, for a small script, it's safe.
