What Roy said... but to prove it to yourself, if you need to,
just implement a little class-variable-based counter in the
File __init__ method to show that you are getting different
objects each time.  (That is, increment a global counter
each time you go through __init__, and store the current
count in the instance, to be retrieved and shown when you
are printing the ids() for the objects.)
