"""
there are three typical ways to define a model in python.
"""


# ---------------------------------------------------
# use namedtuple: simple but not flexible or powerful
# ---------------------------------------------------

from collections import namedtuple

User = namedtuple('User', ['name', 'age', 'email', 'telephone', 'fans'])

user = User(
    name='Tom',
    age=10,
    email='tom@github.com',
    telephone='111-111222',
    fans=[]
)

print(user.name)
# user.name = 'Hey'    # AttributeError

# -------------------------------------------
# create a class: redundant，hard to maintain
# -------------------------------------------

class User(object):
    def __init__(self, name, age, email, telephone, fans=[]):
        self.name = name
        self.age = age
        self.email = email
        self.telephone = telephone
        self.fans = fans


class User(object):
    def __init__(self, data):
        self._data = data

    @property
    def name(self):
        return self._data.get('name', '')
