New submission from John Hagen <johntha...@gmail.com>:
The example for StringIO currently manually closes the object rather than using a context manager. Since this is likely the first code that a new user encounters and context managers reduce error-prone situations, I think it would be helpful to show usage as a context manager. https://docs.python.org/3/library/io.html#io.StringIO.getvalue Something like: import io with io.StringIO() as output: output.write('First line.\n') print('Second line.', file=output) # Retrieve file contents -- this will be # 'First line.\nSecond line.\n' contents = output.getvalue() # Context manager will automatically close # object and discard memory buffer -- # .getvalue() will now raise an exception. ---------- assignee: docs@python components: Documentation messages: 391000 nosy: John Hagen, docs@python priority: normal severity: normal status: open title: Use context manager in StringIO example type: enhancement versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43834> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
