When a file is used as an iterator, typically in a :keyword:`for` loop (for example, ``for line in f: print line``), the - :meth:`next` method is called repeatedly. This method returns the next input + :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. |
