Can you provide a Python code to print >>warnfile, timestamped_msg given the following:
I wrote the below code

    def t_format():
        return int(time.time())
    if (timestamp_format is None):
        timestamp_format = t_format
    def alert(*params):
        formatted_msg = ((msg_type + ' DCTB ') + (msg_template % params))
        timestamped_msg = prepend_timestamp(formatted_msg, timestamp_format)
        print >>warnfile, timestamped_msg
    return alert

What's a good function header?
