I don't think you've demonstrated that; all you've shown is that builtin
Python file objects make file closing idempotent.  You haven't
demonstrated a case where there actually is an I/O error that occurs
when .close gets called.  In particular, I _really_ don't know what you
meant to show with this snippet, as it really has nothing to do with
files at all:
