logging-not-lazy / W1201#
Use %s formatting in logging functions
Used when a logging statement has a call form of "logging.<logging method>(format_string % (format_args...))". Use another type of string formatting instead. You can use % formatting but leave interpolation to the logging function by passing the parameters as arguments. If logging-fstring-interpolation is disabled then you can use fstring formatting. If logging-format-interpolation is disabled then you can use str.format.
import logging try: function() except Exception as e: logging.error('Error occurred: %s' % e) # [logging-not-lazy] raise
import logging try: function() except Exception as e: logging.error('Error occurred: %s', e) raise
Another reasonable option is to use f-strings. If you want to do that, you need to enable
logging-not-lazy and disable
