To truncate a file, open it using ``f = open(filename, "r+")``, and use
``f.truncate(offset)``; offset defaults to the current seek position. There's
-also ```os.ftruncate(fd, offset)`` for files opened with :func:`os.open`, where
+also ``os.ftruncate(fd, offset)`` for files opened with :func:`os.open`, where
``fd`` is the file descriptor (a small integer).
The :mod:`shutil` module also contains a number of functions to work on files

* N (an integer). N args from the command-line will be gathered together into a
list. For example::
- >>> parser = argparse.ArgumentParser()
- >>> parser.add_argument('--foo', nargs=2)
- >>> parser.add_argument('bar', nargs=1)
- >>> parser.parse_args('c --foo a b'.split())
- Namespace(bar=['c'], foo=['a', 'b'])

- Note that ``nargs=1`` produces a list of one item. This is different from
- the default, in which the item is produced by itself.
