Type error: not enough arguments for format string

I'm just trying to follow along with the logging tutorial documentation and I am getting this error:
import logging
logging.basicConfig(format= '%(asctime)s % (message)s', datefmt='%m%d%Y %I:%M:%S %p')
logging.warning('is when this event was logged')
Error:
