[Python] Python logging to stdout and log file

I am fairly new in python and starting to get into the logging module. I would like to have the message logged into a log file and outputting to the console. The code below prints out the message to console but how can I get all the message to be log in a file?

Logger object does not have a function call (basicConfig(filename=)) for logging to a file. How can I add this functionality?

Thanks for the help in advance.

import logging

# create logger
logger = logging.getLogger(_name_)
logger.setLevel(logging.DEBUG)

# create console handler and set level to debug
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)

# create formatter
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

# add formatter to ch
ch.setFormatter(formatter)

# add ch to logger
logger.addHandler(ch)

# 'application' code
logger.debug('debug message')
logger.info('info message')
logger.warn('warn message')
logger.error('error message')
logger.critical('critical message')
