Easy-to-create, lightweight object types.
They allow to fetch an element of the tuple by name, eg person.last_name if last_name would be an element of that namedtuple.
Namedtuples are backwards compatible with normal tuples - so can be called as person[0].
Usage
from collections import namedtuple
# Define namedtupe format and names
person = namedtuple('Person', ['first', 'last'])
# Create a namedtuple
x = person(first='Paul', last='Atreides')
# Call elements of the namedtuple with .
print(x.last)
outputs:
'Atreides'
or return as dict with x._asdict():
print(x._asdict())
outputs:
{'first': 'Paul', 'last': 'Atreides'}
Snippets
Sort list of namedtuples by key
from operator import attrgetter
sorted(list_object, key=attrgetter('release_date'))
