Let me preface my response by saying that this is a really weird thing
to do, and almost certainly _not_ what you want to be doing.  If I was
to run across code like this, I'd be appalled ;-)  Here's one way to
do it, however:

def make_dict(*args):
    d = {}
    for arg in args:
        for key, value in globals().iteritems():
            if value is arg:
                d[key] = value
                break
    return d

Note that this returns a dictionary, rather than a string, but this is
trivial to modify.
