But I don't want to make all log levels go to stdout. Just DEBUG and INFO. But this would be a workaround.

The main question here is why does Python deciecded to make all logs go to stderr? Maybe I totally misunderstood the intention of logging.info()?! Isn't this the "usual applicaton output"?

If not, what messages should go into logging.info()? Can you name me some examples?

Example:

write an app that prints the contents of a file.

The application output is the contents of the file.

The logging might be this when all is working:

INFO About to open <filename>
INFO Wrote <number> bytes from <filename>

The logging might be this when there is a problem:

INFO About to open <filename>
ERROR Failed to open <filename> - <reason>

Does that help?
