Here's a good function header given the following:
I wrote the below code

    for (k, v) in kw.iteritems():
        if (v is True):
            v = k
            k = ''
        try:
            v = int(v)
        except:
            old = v
            v = logging.DEBUG
            def dofail():
                core.getLogger(k).error('Bad    log    level:    %s.    Defaulting    to    DEBUG.', old)
            if ((len(old) == 0) or (len(old.strip(string.ascii_uppercase)) != 0)):
                dofail()
            else:
                vv = getattr(logging, old, None)
                if (not isinstance(vv, int)):
                    dofail()
                else:
                    v = vv
        core.getLogger(k).setLevel(v)

What's a good function header?
