When I run this code:

import logging

if __name__ == "__main__":
  logger = logging.getLogger(__name__)
  logger.setLevel(logging.INFO)
  logger.info("INFO message")
  logger.debug("DEBUG message")
  logger.warning("WARNING message")
  logger.error("ERROR message")

I get the following output:

WARNING message
ERROR message

I come I don't see the INFO and DEBUG messages?

Unduping. Neither the dupe target nor Brian's links explain what's going on here. – user2357112 Mar 21 '22 at 15:09

Found a better dupe target. – user2357112 Mar 21 '22 at 15:10
Just to note, you don't see a similar problem when you use the module-level functions `logging.info`, etc, because they implicitly call `logging.basicConfig` if no handlers are detected. – chepner Mar 21 '22 at 15:17
