The main information passed in is in msg and args, which are combined using str(msg) % args to create the message field of the record.

This method should be called from format() by a formatter which wants to make use of a formatted time. This method can be overridden in formatters to provide for any specific requirement, but the basic behaviour is as follows: if datefmt (a string) is specified, it is used with time.strftime() to format the creation time of the record. Otherwise, an ISO8601-like (or RFC 3339-like) format is used. The resulting string is returned. This function uses a user-configurable function to convert the creation time to a tuple. By default, time.localtime() is used; to change this for a particular formatter instance, set the 'converter' attribute to a function with the same signature as time.localtime() or time.gmtime(). To change it for all formatters, for example if you want all logging times to be shown in GMT, set the 'converter' attribute in the Formatter class. )Ú converterruraÚstrftimeÚdefault_time_formatÚdefault_msec_formatrv)rr¡rÆr…ÚsÚtr7r7r8Ú formatTimeLs  zFormatter.formatTimecCsZt ¡}|d}t |d|d|d|¡| ¡}| ¡|dd…dkrV|dd…}|S)z§ Format and return the specified exception information as a string.

A "logging channel" indicates an area of an application. Exactly how an "area" is defined is up to the application developer. Since an application can have any number of areas, logging channels are identified by a unique string. Application areas can be nested (e.g. an area of "input processing" might include sub-areas "read CSV files", "read XLS files" and "read Gnumeric files"). To cater for this natural nesting, channel names are organized into a namespace hierarchy where levels are separated by periods, much like the Java or Python package namespace. So in the instance given above, channel names might be "input" for the upper level, and "input.csv", "input.xls" and "input.gnu" for the sub-levels. There is no arbitrary limit to the depth of nesting. cCs<t |¡||_t|ƒ|_d|_d|_g|_d|_i|_ dS)zJ Initialize the logger with a name and an optional level.

This function does nothing if the root logger already has handlers configured, unless the keyword argument *force* is set to ``True``. It is a convenience method intended for use by simple scripts to do one-shot configuration of the logging package. The default behaviour is to create a StreamHandler which writes to sys.stderr, set a formatter using the BASIC_FORMAT format string, and add the handler to the root logger. A number of optional keyword arguments may be specified, which can alter the default behaviour. filename Specifies that a FileHandler be created, using the specified filename, rather than a StreamHandler. filemode Specifies the mode to open the file, if filename is specified (if filemode is unspecified, it defaults to 'a'). format Use the specified format string for the handler. datefmt Use the specified date/time format. style If a format string is specified, use this to specify the type of format string (possible values '%', '{', '$', for %-formatting, :meth:`str.format` and :class:`string.Template` - defaults to '%'). level Set the root logger level to the specified level. stream Use the specified stream to initialize the StreamHandler. Note that this argument is incompatible with 'filename' - if both are present, 'stream' is ignored. handlers If specified, this should be an iterable of already created handlers, which will be added to the root handler. Any handler in the list which does not have a formatter assigned will be assigned the formatter created in this function. force If this keyword is specified as true, any existing handlers attached to the root logger are removed and closed, before carrying out the configuration as specified by the other arguments. Note that you could specify a stream created using open(filename, mode) rather than passing the filename and mode in. However, it should be remembered that StreamHandler does not close its stream (since it may be using sys.stdout or sys.stderr), whereas FileHandler closes its stream when the handler is closed. .. versionchanged:: 3.8 Added the ``force`` parameter. .. versionchanged:: 3.2 Added the ``style`` parameter. .. versionchanged:: 3.3 Added the ``handlers`` parameter. A ``ValueError`` is now thrown for incompatible arguments (e.g. ``handlers`` specified together with ``filename``/``filemode``, or ``filename``/``filemode`` specified together with ``stream``, or ``handlers`` specified together with ``stream``.
