It's sometimes common in Python to see __init__ code like this:
class SomeClass(object):
def __init__(self, a, b, c, d, e, f, g):
self.a = a
self.b = b
self.c = c
self.d = d
self.e = e
self.f = f
self.g = g
especially if the class in question is purely a data structure with no behaviour. Is there a (Python 2.7) shortcut for this or a way to make one?

Class constructors are a fundamental part of object-oriented programming in Python. They allow you to create and properly initialize objects of a given class, making those objects ready to use.
Python property() function returns the object of the property class and it is used to create property of a class. Parameters: fget() – used to get the value of attribute. fset() – used to set the value of attribute.
type is a metaclass, of which classes are instances. Just as an ordinary object is an instance of a class, any new-style class in Python, and thus any class in Python 3, is an instance of the type metaclass. In the above case: x is an instance of class Foo . Foo is an instance of the type metaclass.
What is a Constructor in Python? A constructor can simply be defined as a special type of method or function which can be used to initialize instances of various members in a class.
You could use Alex Martelli's Bunch recipe:
class Bunch(object):
"""
foo=Bunch(a=1,b=2)
"""
def __init__(self, **kwds):
self.__dict__.update(kwds)
