Is there a Python shortcut for an __init__ that simply sets properties? [duplicate]

Question

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?

Answer 1

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)
