A close sibling is logging.getLogger(), which returns a logger with the specified name or the root logger if name is None. A close sibling is logger.debug(), which logs a message with severity DEBUG (detailed diagnostic info). A close sibling is logger.info(), which logs a message with severity INFO (general operational messages). More about this category: Logging facility — basicConfig, getLogger, FileHandler, Formatter.
