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

    def wrapped(*args, **kwargs):
        '\n                                This    manages    the    function    wrapping,    by    determining    whether    to    inject\n                                the    _external    signup    or    just    continuing    to    the    internal    function\n                                call.\n                                '
        if (not settings.FEATURES['AUTH_USE_CERTIFICATES']):
            return func(*args, **kwargs)
        request = args[0]
        if (request.user and request.user.is_authenticated()):
            return func(*args, **kwargs)
        cert = ssl_get_cert_from_request(request)
        if (not cert):
            return func(*args, **kwargs)
        def retfun():
            'Wrap    function    again    for    call    by    _external_login_or_signup'
            return func(*args, **kwargs)
        (_user, email, fullname) = _ssl_dn_extract_info(cert)
        return _external_login_or_signup(request, external_id=email, external_domain='ssl:MIT', credentials=cert, email=email, fullname=fullname, retfun=retfun)
    return wrapped

What's a good function header?
