小编典典

你可以使用我刚刚制作的此类来做。通过此类，你可以Map像其他字典（包括json序列化）一样使用该对象，也可以使用点符号。希望对你有所帮助：

class Map(dict):

"""

Example:

m = Map({'first_name': 'Eduardo'}, last_name='Pool', age=24, sports=['Soccer'])

"""

def __init__(self, *args, **kwargs):

super(Map, self).__init__(*args, **kwargs)

for arg in args:

if isinstance(arg, dict):

for k, v in arg.iteritems():

self[k] = v

if kwargs:

for k, v in kwargs.iteritems():

self[k] = v

def __getattr__(self, attr):

return self.get(attr)

def __setattr__(self, key, value):

self.__setitem__(key, value)

def __setitem__(self, key, value):

super(Map, self).__setitem__(key, value)

self.__dict__.update({key: value})

def __delattr__(self, item):

self.__delitem__(item)

def __delitem__(self, key):

super(Map, self).__delitem__(key)

del self.__dict__[key]

用法示例：

m = Map({'first_name': 'Eduardo'}, last_name='Pool', age=24, sports=['Soccer'])

# Add new key

m.new_key = 'Hello world!'

# Or

m['new_key'] = 'Hello world!'

print m.new_key

print m['new_key']

# Update values

m.new_key = 'Yay!'

# Or

m['new_key'] = 'Yay!'

# Delete key

del m.new_key

# Or

del m['new_key']
