>>>
>>> Animal = namedtuple('Animal', 'name species sex')
>>> # Animal = namedtuple('Animal', ['name','species','sex'])
... # Animal = namedtuple('Animal', ('name','species','sex'))
... a = Animal('pororo', 'penguin', 'male')

>>> a
Animal(name='pororo', species='penguin', sex='male')

'pororo'

'pororo'

'male'
