最佳答案
I want to sort a list of named tuples without having to remember the index of the fieldname. My solution seems rather awkward and was hoping someone would have a more elegant solution.
from operator import itemgetter
from collections import namedtuple
Person = namedtuple('Person', 'name age score')
seq = [
Person(name='nick', age=23, score=100),
Person(name='bob', age=25, score=200),
]
# sort list by name
print(sorted(seq, key=itemgetter(Person._fields.index('name'))))
# sort list by age
print(sorted(seq, key=itemgetter(Person._fields.index('age'))))
Thanks, Nick
