from collections import namedtuple

People = namedtuple("People",["Name","Age"])

Lists = [People("Maca","24"),People("Puma","18"),People("Lula","30")]

print Lists

Lists.sort(key=lambda args:args.Age)

print Lists

Lists.sort(key=lambda args:args.Name)

print Lists

Outputs:

[People(Name='Maca', Age='24'), People(Name='Puma', Age='18'), People(Name='Lula', Age='30')]

[People(Name='Puma', Age='18'), People(Name='Maca', Age='24'), People(Name='Lula', Age='30')]

[People(Name='Lula', Age='30'), People(Name='Maca', Age='24'), People(Name='Puma', Age='18')]
