lzma.decompress(data, format=FORMAT_AUTO, memlimit=None, filters=None) Decompress data (a bytes object), returning the uncompressed data as a bytes object. If data is the concatenation of multiple distinct compressed streams, decompress all of these streams, and return the concatenation of the results. See LZMADecompressor above for a description of the format, memlimit and filters arguments.

lzma.compress(data, format=FORMAT_XZ, check=-1, preset=None, filters=None) Compress data (a bytes object), returning the compressed data as a bytes object. See LZMACompressor above for a description of the format, check, preset and filters arguments.

exception LookupError The base class for the exceptions that are raised when a key or index used on a mapping or sequence is invalid: IndexError, KeyError. This can be raised directly by codecs.lookup().

logging.warning(msg, *args, **kwargs) Logs a message with level WARNING on the root logger. The arguments are interpreted as for debug(). Note There is an obsolete function warn which is functionally identical to warning. As warn is deprecated, please do not use it - use warning instead.

flush() Flushes the stream by calling its flush() method. Note that the close() method is inherited from Handler and so does no output, so an explicit flush() call may be needed at times.

emit(record) If a formatter is specified, it is used to format the record. The record is then written to the stream with a terminator. If exception information is present, it is formatted using traceback.print_exception() and appended to the stream.

class logging.StreamHandler(stream=None) Returns a new instance of the StreamHandler class. If stream is specified, the instance will use it for logging output; otherwise, sys.stderr will be used. emit(record) If a formatter is specified, it is used to format the record. The record is then written to the stream with a terminator. If exception information is present, it is formatted using traceback.print_exception() and appended to the stream. flush() Flushes the stream by calling it

logging.shutdown() Informs the logging system to perform an orderly shutdown by flushing and closing all handlers. This should be called at application exit and no further use of the logging system should be made after this call.

logging.setLogRecordFactory(factory) Set a callable which is used to create a LogRecord. Parameters: factory – The factory callable to be used to instantiate a log record. New in version 3.2: This function has been provided, along with getLogRecordFactory(), to allow developers more control over how the LogRecord representing a logging event is constructed. The factory has the following signature: factory(name, level, fn, lno, msg, args, exc_info, func=None, sinfo=None, **kwargs) name:

logging.setLoggerClass(klass) Tells the logging system to use the class klass when instantiating a logger. The class should define __init__() such that only a name argument is required, and the __init__() should call Logger.__init__(). This function is typically called before any loggers are instantiated by applications which need to use custom logger behavior.
