namedtuple instance are just as memory efficient as regular tuples because they do not have per-instance dictionaries. Each kind of namedtuple is represented by its own class.



In [2]:

    
import collections

Person = collections.namedtuple('Person', 'name age')

bob = Person(name='Bob', age=30)
print('\nRepresentation:', bob)

jane = Person(name='Jane', age=29)
print('\nField by name:', jane.name)

print('\nFields by index:')
for p in [bob, jane]:
    print('{} is {} years old'.format(*p))









    



Representation: Person(name='Bob', age=30)

Field by name: Jane

Fields by index:
Bob is 30 years old
Jane is 29 years old
