Logger.makeRecord(name, lvl, fn, lno, msg, args, exc_info, func=None, extra=None, sinfo=None) This is a factory method which can be overridden in subclasses to create specialized LogRecord instances.

xml.parsers.expat.errors.codes A dictionary mapping numeric error codes to their string descriptions. New in version 3.2.

csv.field_size_limit([new_limit]) Returns the current maximum field size allowed by the parser. If new_limit is given, this becomes the new limit.

timezone.dst(dt) Always returns None.

curses.endwin() De-initialize the library, and return terminal to normal status.

math.atanh(x) Return the inverse hyperbolic tangent of x.

os.ftruncate(fd, length) Truncate the file corresponding to file descriptor fd, so that it is at most length bytes in size. As of Python 3.3, this is equivalent to os.truncate(fd, length). Availability: Unix, Windows. Changed in version 3.5: Added support for Windows

os.getenv(key, default=None) Return the value of the environment variable key if it exists, or default if it doesn’t. key, default and the result are str. On Unix, keys and values are decoded with sys.getfilesystemencoding() and 'surrogateescape' error handler. Use os.getenvb() if you would like to use a different encoding. Availability: most flavors of Unix, Windows.

time.ctime([secs]) Convert a time expressed in seconds since the epoch to a string representing local time. If secs is not provided or None, the current time as returned by time() is used. ctime(secs) is equivalent to asctime(localtime(secs)). Locale information is not used by ctime().
