.. _logging-not-lazy: logging-not-lazy / W1201 ======================== **Message emitted:** Use %s formatting in logging functions **Description:** *Used when a logging statement has a call form of "logging.(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.* Created by ``logging`` checker
