New submission from Yuta Okamoto <okapies@gmail.com>: I noticed that Configurators in logging.config module accepts '.' (dot) as a key to fill attributes for filters, formatters, and handlers directly like the following: handlers: syslog: class: logging.handlers.SysLogHandler .: ident: 'app-name: ' https://github.com/python/cpython/blob/46abfc1416ff8e450999611ef8f231ff871ab... But it seems this functionality is not documented in https://docs.python.org/3/library/logging.config.html ---------- assignee: docs@python components: Documentation messages: 363744 nosy: Yuta Okamoto, docs@python priority: normal severity: normal status: open title: logging.config: '.'
