A file object is its own iterator, for example ``iter(f)`` returns *f* (unless

+ :meth:`next` method is called repeatedly. This method returns the next input
line, or raises :exc:`StopIteration` when EOF is hit when the file is open for
reading (behavior is undefined when the file is open for writing). In order to
make a :keyword:`for` loop the most efficient way of looping over the lines of a
file (a very common operation), the :meth:`next` method uses a hidden read-ahead
- buffer. As a consequence of using a read-ahead buffer, combining :meth:`.next`
+ buffer. As a consequence of using a read-ahead buffer, combining :meth:`next`
with other file methods (like :meth:`readline`) does not work right. However,
using :meth:`seek` to reposition the file to an absolute position will flush the
read-ahead buffer.
