def parse(value, base='sqla'):
''' Convenience function to returned a parsed expression
Returns a parsed string using one of the available Parsers
in `boolean_parser`. The ``base`` keyword argument can be used
to select which ``Parser`` to use. The availble bases are: "base",
"sqla". The default base is "sqla" which uses the :py:class:`boolean_parser.parsers.sqla.SQLAParser`.
Parameters:
value: str
The string expression to evaluate and parse
base: str:
The base Parser to use. Default is sqlalchemy parser.
Returns:
A parsed string using a :ref:`api-parsers` object.
