logging.getLoggerClass()

loggers

Returns the class getLogger() instantiates: Logger by default, or your subclass after setLoggerClass().

Syntax

cls = logging.getLoggerClass()

Derive your logger subclass from getLoggerClass() rather than Logger: if a library has already installed its own class, you extend it instead of throwing it away. The result only describes future loggers — those already created keep their class. The root logger is always a RootLogger and is unaffected.

Examples

import logging
print(logging.getLoggerClass().__name__)  # → Logger
print(type(logging.getLogger()).__name__)  # → RootLogger
