Usage Notes: Here are some general conventions when accessing the low level inspector methods such as get_table_names, get_columns, etc. 1. Inspector methods return lists of dicts in most cases for the following reasons: * They're both standard types that can be serialized. * Using a dict instead of a tuple allows easy expansion of attributes. * Using a list for the outer structure maintains order and is easy to work with (e.g. list comprehension [d['name'] for d in cols]). 2. Records that contain a name, such as the column name in a column record use the key 'name'. So for most return values, each record will have a 'name' attribute.. i ( t Connectablei ( t exc( t inspection( t sql( t util( t operators( t schema( t TypeEngine( t deprecated( t topologicalc O s� | j d d � } | d k r1 | | | | | � S| j t d � | D� � t d � | j � D� � f } | j | � } | d k r� | | | | | � } | | | <n | S( Nt info_cachec s s'
