Python的namedtuple使用

from collections import namedtuple

# Each kind of nametuple is represented by its own class,
# created by using the nametuple() factory function

# containing the names of the elements

Person = namedtuple('Person', 'name age gender')

print 'Type of Person:', type(Person)

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

jane = Person(name='Jane', age=29, gender='female')

    print '%s is a %d year old %s' % p
