Return the textual representation of logging level 'level'.
If the level is one of the predefined levels (CRITICAL, ERROR, WARNING,
INFO, DEBUG) then you get the corresponding string. If you have
associated levels with names using addLevelName then the name you have
associated with 'level' is returned.
If a numeric value corresponding to one of the defined levels is passed
in, the corresponding string representation is returned.
Otherwise, the string "Level %s" % level is returned.

A LogRecord instance represents an event being logged.
LogRecord instances are created every time something is logged. They
contain all the information pertinent to the event being logged. 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. The
record also includes information such as when the record was created,
the source line where the logging call was made, and any exception
information to be logged.

Formatter instances are used to convert a LogRecord to text.
Formatters need to know how a LogRecord is constructed. They are
responsible for converting a LogRecord to (usually) a string which can
be interpreted by either a human or an external system. The base Formatter
allows a formatting string to be specified. If none is supplied, the
default value of "%s(message)\n" is used.
The Formatter can be initialized with a format string which makes use of
knowledge of the LogRecord attributes - e.g. the default value mentioned
above makes use of the fact that the user's message and arguments are pre-
formatted into a LogRecord's message attribute. Currently, the useful
attributes in a LogRecord are described by:
%(name)s Name of the logger (logging channel)
%(levelno)s Numeric logging level for the message (DEBUG, INFO,
WARNING, ERROR, CRITICAL)
%(levelname)s Text logging level for the message ("DEBUG", "INFO",
"WARNING", "ERROR", "CRITICAL")
%(pathname)s Full pathname of the source file where the logging
call was issued (if available)
%(filename)s Filename portion of pathname
%(module)s Module (name portion of filename)
%(lineno)d Source line number where the logging call was issued
(if available)
%(funcName)s Function name
%(created)f Time when the LogRecord was created (time.time()
return value)
%(asctime)s Textual time when the LogRecord was created
%(msecs)d Millisecond portion of the creation time
%(relativeCreated)d Time in milliseconds when the LogRecord was created,
relative to the time the logging module was loaded
(typically at application startup time)
%(thread)d Thread ID (if available)
%(threadName)s Thread name (if available)
%(process)d Process ID (if available)
%(message)s The result of record.getMessage(), computed just as
the record is emitted
c C s( | r | | _ n d | _ | | _ d S( s8
Initialize the formatter with specified format strings.
Initialize the formatter either with the specified format string, or a
default as described above. Allow for specialized date formatting with
the optional datefmt argument (if omitted, you get the ISO8601 format).

Return the creation time of the specified LogRecord as formatted text.
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, the ISO8601 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.

Format the specified record as text.
The record's attribute dictionary is used as the operand to a
string formatting operation which yields the returned string.
Before formatting the dictionary, a couple of preparatory steps
are carried out. The message attribute of the record is computed
using LogRecord.getMessage(). If the formatting string uses the
time (as determined by a call to usesTime(), formatTime() is
called to format the event time. If there is exception information,
it is formatted using formatException() and appended to the message.

Filter instances are used to perform arbitrary filtering of LogRecords.
Loggers and Handlers can optionally use Filter instances to filter
records as desired. The base filter class only allows events which are
below a certain point in the logger hierarchy. For example, a filter
initialized with "A.B" will allow events logged by loggers "A.B",
"A.B.C", "A.B.C.D", "A.B.D" etc. but not "A.BB", "B.A.B" etc. If
initialized with the empty string, all events are passed.

Handle errors which occur during an emit() call.
This method should be called from handlers when an exception is
encountered during an emit() call. If raiseExceptions is false,
exceptions get silently ignored. This is what is mostly wanted
for a logging system - most users will not care about errors in
the logging system, they are more interested in application errors.
You could, however, replace this with a custom handler if you wish.
The record which was being processed is passed in to this method.

Instances of the Logger class represent a single logging channel. 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.

Do basic configuration for the logging system.
This function does nothing if the root logger already has handlers
configured. 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.
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.
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.

important for library code, which may contain code to log events. If a user
