Python logger DEBUG is not shown

Question

Given this setup, I cannot see any debug logs:

import logging
import coloredlogs

coloredlogs.install(isatty=True)

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

# Show the current debug level
logger.critical(logger.level)


logger.critical("critical")
logger.error("error")
logger.warning("warning")
logger.info("info")
logger.debug("debug") <-- NOT SHOWN!

Yet if I change to coloredlogs.install(level=logging.DEBUG,isatty=True)

I get all the DEBUG notices but they include other libs debug messages (botocore, urllib..) which is unwanted since I want to see only my debug notices.

What did I miss?

Have you tried:

logging.basicConfig(level=logging.DEBUG)

instead of logger.setLevel? I assume you only set the level of that logger, but the corresponding handlers still have a higher level, so the message is ignored.

Not working, but 'coloredlogs.install(level=logging.DEBUG,isatty=True)' Does the job, but it shows a lot more debugging, even for external libs which is unwanted.
