'230 Guest login ok, access restrictions apply.'

    To create a connection, call the class using these arguments:
            host, user, passwd, acct, timeout

    The first four arguments are all strings, and have default value ''.
    timeout must be numeric and defaults to None if not passed,
    meaning that no timeout will be set on any ftp socket(s)
    If a timeout is passed, then this is now the default timeout for all ftp
    socket operations for this instance.

    Then use self.connect() with optional host and port argument.

    To download a file, use ftp.retrlines('RETR ' + filename),
    or ftp.retrbinary() with slightly different arguments.
    To upload a file, use ftp.storlines() or ftp.storbinary(),
    which have an open file as argument (see their definitions
    below for details).
    The download/upload functions first issue appropriate TYPE
    and PORT or PASV commands.

        in RFC-4217.

        Connect as usual to port 21 implicitly securing the FTP control
        connection before authenticating.

        Securing the data connection requires user to explicitly ask
        for it by calling prot_p() method.

        Usage example:
        >>> from ftplib import FTP_TLS
        >>> ftps = FTP_TLS('ftp.python.org')
        >>> ftps.login()  # login anonymously previously securing control channel
        '230 Guest login ok, access restrictions apply.'
        >>> ftps.prot_p()  # switch to secure data connection
        '200 Protection level set to P'
        >>> ftps.retrlines('LIST')  # list directory content securely
