If `logger_name` is a hierarchy format (e.g. `logger_name = 'parent.child'`) and the logger name `'parent'` has not been created, the function call `logging.getLogger(logger_name)` will create all loggers in the hierarchy (in this instance two loggers, `'parent'` and `'parent.child'` will be created) This is not documented anywhere in the logging documentation. Suggest that this is detailed under `logging.getLogger` More info... https://stackoverflow.com/q/59990300/4013571 |

That's an internal detail. In fact loggers aren't created for all loggers in the hierarchy - PlaceHolder objects are created internally for hierarchy ancestors, and converted to loggers if needed. The printout from your linked Stack Overflow question shows this. This is not documented because it's internal implementation detail. How the dotted-name hierarchy works is documented. |
