The real example would be more like:

ouch.
if you do this a lot (=more than once), just wrap your dictionaries in a
simple attribute proxy, and use plain attribute access. that is, given
class AttributeWrapper:
def __init__(self, obj):
self.obj = obj
def __getattr__(self, name):
try:
return self.obj[name]
except KeyError:
raise AttributeError(name)
or, shorter but less obvious and perhaps a bit too clever for a
beginning Pythoneer:
class AttributeWrapper:
def __init__(self, obj):
self.__dict__.update(obj)
you can do
>>> some_data = dict(name="Some Name", age=123, country="SE")
>>> some_data
{'country': 'SE', 'age': 123, 'name': 'Some Name'}
>>> this = AttributeWrapper(some_data)
>>> this.name
'Some Name'
>>> this.age
123
>>> this.country
'SE'
and, if you must, assign the attributes to local variables like this:
>>> name, age, country = this.name, this.age, this.country
>>> name
'Some Name'
>>> age
123
>>> country
'SE'
>>>
(the next step towards true Pythonicness would be to store your data in
class instances instead of dictionaries in the first place, but one step
at a time...)
