String-based indices in tuple Python

Question

Is it possible to create a tuple in Python with indices that are string-based, not number based? That is, if I have a tuple of ("yellow", "fish", "10) , I would be able to access by [color] instead of [0] . This is really only for the sake of convenience.

Answer 1

You can use collections.namedtuple() :

>>> from collections import namedtuple
>>> MyObject = namedtuple('MyObject', 'color number')
>>> my_obj = MyObject(color="yellow", number=10)
>>> my_obj.color
'yellow'
>>> my_obj.number
10

And you can still access items by index:

>>> my_obj[0]
'yellow'
>>> my_obj[1]
10

Answer 2

是的，尽管您将使用x.color而不是x['color']访问颜色，但collections.namedtuple执行此操作
