The multiprocessing module includes a relatively simple API for dividing work up between multiple processes. It is based on the API for threading, and in some cases is a drop-in replacement. Due to the similarity, the first few examples here are modified from the threading examples. This method checks first the module-level level set by logging.disable (level) and then the logger's effective level as determined by getEffectiveLevel (). getEffectiveLevel () ¶ Indicates the effective level for this logger.
