Map **kwargs to attributes

Here you can see, how to map **kwargs to your attributes:

class Xex(KwargsObj):
    def __init__(self, **kwargs):
        self.something = None
        self.something_else = None

        self._kwargs_to_attributes(kwargs)

This will allow to pass parameters which sets something_else and something_different:

>>> x = Xex(something=True)
>>> x.something
True

Setting of unset attributes is dissabled:

>>> x = Xex(asd=True)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 5, in __init__
  File "kwargs_obj/kwargs_obj.py", line 61, in _kwargs_to_attributes
    "Can't set %s parameter - it is not defined here!" % key
ValueError: Can't set asd parameter - it is not defined here!

Disable setting of unset attributes

There is also modified .__setattr__()` method, which disables to set new attributes. This may be good idea for data containers.

Modified .__setattr__() functionality can be triggered by setting the ._all_set attribute:

class Xex(KwargsObj):
    def __init__(self):
        self.something = None
        self.something_else = None

        self._all_set = True

It will be now impossible to set new attributes, which may be good for preventing typos:

>>> x = Xex()
>>> x.asd = True
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "kwargs_obj/kwargs_obj.py", line 50, in __setattr__
    raise ValueError("%s is not defined in this class!" % name)
ValueError: asd is not defined in this class!

But you can still redefine already defined attributes:

>>> x.something = True
>>>
