A file name which the contents of will be appended to the ArticleText when posting articles.
def get_attached_file() -> str: ... def set_attached_file(value: str) -> None: ...
attached_file = property(get_attached_file, set_attached_file)
The content of this property is appended to the text in article_text (if any) and sent to the news server. This property is useful for posting arbitrarily large articles and/or sending MIME attachments.
It is advisable that the text contained in the file be a collection of lines with lengths less than or equal to 80 bytes separated by CRLF ("\r\n") . The text in the message lines must contain only 7-bit characters so that the message may be successfully sent through the various Usenet news servers on the Internet.
The class automatically escapes lines that start with a "." by adding another as specified in RFC 822. The article text is unescaped by the news server, so the process is fully transparent.
