Return the textual or numeric 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.
If a string representation of the level is passed in, the corresponding
numeric value is returned.
If no matching numeric or string value is passed in, 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.

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 datefmt is omitted, you get an
ISO8601-like (or RFC 3339-like) format.
Use a style parameter of '%', '{' or '$' to specify that you want to
use one of %-formatting, :meth:`str.format` (``{}``) formatting or
:class:`string.Template` formatting in your format string.

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, 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.

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.

Emit a record.
If a formatter is specified, it is used to format the record.
The record is then written to the stream with a trailing newline. If
exception information is present, it is formatted using
traceback.print_exception and appended to the stream. If the stream
has an 'encoding' attribute, it is used to determine how to do the
output to the stream.

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, 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``.

This handler does nothing. It's intended to be used to avoid the
"No handlers could be found for logger XXX" one-off warning. This is
important for library code, which may contain code to log events. If a user
of the library does not configure logging, the one-off warning might be
produced; to avoid this, the library developer simply needs to instantiate
a NullHandler and add it to the top-level logger of the library module or
package.

Implementation of showwarnings which redirects to logging, which will first
check to see if the file parameter is None. If a file is specified, it will
delegate to the original warnings implementation of showwarning. Otherwise,
it will call warnings.formatwarning and will log the resulting string to a
warnings logger named "py.warnings" with level logging.WARNING.

If capture is true, redirect all warnings to the logging package.
If capture is False, ensure that warnings are not redirected to logging
but to their original destinations.
