root-logger-call (LOG015)

Derived from the flake8-logging linter.

This rule is unstable and in preview. The --preview flag is required for use.

What it does

Checks for usages of the following logging top-level functions: debug, info, warn, warning, error, critical, log, exception.

Why is this bad?

Using the root logger causes the messages to have no source information, making them less useful for debugging.

Example

import logging

logging.info("Foobar")

Use instead:

import logging

logger = logging.getLogger(__name__)
logger.info("Foobar")
