What is the best way to do automatic attribute assignment in Python, and is it a good idea?

Question

Instead of writing code like this every time I define a class:

class Foo(object): 
     def __init__(self, a, b, c, d, e, f, g):
        self.a = a
        s

Similar to the above, though not the same... the following is very short, deals with args and kwargs:

def autoassign(lcls):
    for key in lcls.keys():
        if key!="self":
            lcls["self"].__dict__[key]=lcls[key]

Use like this:

class Test(object):
    def __init__(self, a, b, *args, **kwargs):
        autoassign(locals())
