list - Issue overriding __get__ in Python -

i have class:

from collections import userlist   class itemlist(userlist):     data = []      def __init__(self, contents):         self.data = contents      def __get__(self, index):         result = list.__get__(self, index)         if type(result) list:             if len(result) > 1:                 return itemlist(result)         else:             return result 

it seems in case get isn't being called when index instance of itemlist class. i'm trying return new instance of itemclass if result of index returns more 1 item (a list). expect this:

>>> il = itemlist(contents) >>> type(il[1:3]) <class 'itemlist'> 

but i'm getting this:

>>> il = itemlist(contents) >>> type(il[1:3]) <class 'list'> 

what doing wrong?

i think want more following:

class itemlist(userlist):     data = []     def __init__(self, contents):         super().__init__()         self.data = contents     def __getitem__(self, item):         result = userlist.__getitem__(self, item)         if type(result) list:             if len(result) > 1:                 return itemlist(result)         else:             return result
