Description:
 def lines(self, encoding=None, errors='strict', retain=True):
 r""" Open this file, read all lines, return them in a list. Optional arguments: `encoding` - The Unicode encoding (or character set) of the file. The default is ``None``, meaning the content of the file is read as 8-bit characters and returned as a list of (non-Unicode) str objects. `errors` - How to handle Unicode errors; see help(str.decode) for the options. Default is ``'strict'``. `retain` - If ``True``, retain newline characters; but all newline character combinations (``'\r'``, ``'\n'``, ``'\r\n'``) are translated to ``'\n'``. If ``False``, newline characters are stripped off. Default is ``True``. .. seealso:: :meth:`text` """
