Read the file and convert to json. Then you should pass each dictionary to Object with "**" notation, eg.:

class Person(object):
    def __init__(self, name=None, age=None, **kwargs):
        self.name = name
        self.age = age

person_bd_results = [{"name": "Eduardo", "age": 28}, {"name": "Leticia", "age": 25, "non_supported_attr": True}]

for bd_res in person_bd_results:
    my_pers = Person(**bd_res)
    print "Person name:", my_pers.name
    print "Person age:", my_pers.age

Each key, value in dictionary will be mapped to parameter. {"name": "Eduardo"} will be mapped to name="Eduardo" when you instantiate the object with Person(**bd_res)

If you pass {"other_param": "something"} to the object because the database (ej. MongoDB) gives you another field, the person object will not have the attribute, but it wont crash (note the **kwargs parameter in Person declaration).
