• loglevel – Loglevel to use when writing messages.

close()

When the object is closed, no write requests are forwarded to the logging object anymore.

fileno()

flush()

isatty()

Always returns False. Just here for file support.

write(data)

writelines(sequence)

writelines(sequence_of_strings) -> None.

Write the strings to the file.

The sequence can be any iterable object producing strings. This is equivalent to calling write() for each string.
