ValueError: I/O operation on closed file
+It is good practice to use the :keyword:`with` keyword when dealing with file
+objects. This has the advantage that the file is properly closed after its
+suite finishes, even if an exception is raised on the way. It is also much
+shorter than writing equivalent :keyword:`try`\ -\ :keyword:`finally` blocks::
+ >>> with open('/tmp/workfile', 'r') as f:
+ ... read_data = f.read()
File objects have some additional methods, such as :meth:`isatty` and
:meth:`truncate` which are less frequently used; consult the Library Reference
for a complete guide to file objects.
