I wrote the below code

    def cancel(deferred):
        '\n                                Cancel    a    L{readBody}    call,    close    the    connection    to    the    HTTP    server\n                                immediately,    if    it    is    still    open.\n\n                                @param    deferred:    The    cancelled    L{defer.Deferred}.\n                                '
        abort = getAbort()
        if (abort is not None):
            abort()
    d = defer.Deferred(cancel)
    protocol = _ReadBodyProtocol(response.code, response.phrase, d)
    def getAbort():
        return getattr(protocol.transport, 'abortConnection', None)
    response.deliverBody(protocol)
    if ((protocol.transport is not None) and (getAbort() is None)):
        warnings.warn('Using    readBody    with    a    transport    that    does    not    have    an    abortConnection    method', category=DeprecationWarning, stacklevel=2)
    return d

What's a good function header?
