Why there is always a ‘#’ when I use my logger even propagation is off already?

[oglop]

import logging
_logger = logging.getLogger('myLogger')

for handler in _logger.handlers:
    _logger.removeHandler(handler)

ch = logging.StreamHandler()
ch.setLevel(logging.INFO)
formatter = logging.Formatter('%(name)s:%(levelname)s: %(message)s')
ch.setFormatter(formatter)
_logger.addHandler(ch)
_logger.propagate=0

_logger.info('yeah')
# myLogger:INFO: yeah

I have set propagate to off already, where does the '#' come from when I use _logger in maya 2015?

It is because your logging is going to stderr, and Maya assigns a custom stderr and hides the original one:

import sys

# Maya installs this one so it goes to Script Editor
sys.stderr.write("stderr\n")

# The original one that Maya saves
sys.__stderr__.write("__stderr__\n")

Thanks! After changing this line to

ch = logging.StreamHandler(sys.stdout)

The '#' goes away.
