How to print something in command line/console in from Blender?

I wrote some script which renders scenes and want see output on console I am using print but it not works what I should use to print something.

I run script with:

blender -b -P render.py

Want output such string from render.py:

print '#' * 80

It is little trivial question but print not works and not know how to progress development without debug messages.

use the logging module to setup your custom logger.

you can setup a Console handler to log the content to the console or/and

formatter = logging.Formatter('%(message)s')
console_handler = logging.StreamHandler(sys.stdout)
console_handler.setFormatter(formatter)

setup a File handler if you want to log to a file:

file_handler = logging.FileHandler(log_file)
file_handler.setFormatter(formatter)

# Add the handler to the logger:
logger.addHandler(console_handler)
logger.addHandler(file_handler)

They can both have different log levels which you can set via script or environement variable:

log_level = level
if 'LOG_LEVEL' in os.environ:
    log_level = os.environ['LOG_LEVEL']
console_handler.setLevel(log_level)
file_handler.setLevel('INFO')
